Legal rules for laying hen farming
Before you place the first hens, the farm must be registered, and you must meet welfare and Salmonella-testing requirements and mark eggs correctly by farming method. We have gathered the whole map of duties in one place — in plain language, with links to detailed pages. This is an informational guide, not binding legal advice: the law changes, so confirm key points with your local veterinary officer and the agricultural agency.

Laying hen farming in Poland is more than egg production — it is also a set of duties towards the authorities. Before you place the first hens the farm must be registered, and you must meet welfare, flock-health and correct egg-marking requirements. This page is an overview — a map of duties showing what to arrange and where, and pointing to separate guides for the details. The whole process is covered in the hub on laying hen farming.
Where do these rules come from?
Most welfare requirements come from EU law — the key one for layers is Council Directive 1999/74/EC laying down minimum standards for the protection of laying hens. Since 2012 it has banned conventional (battery) cages in the EU and allows only enriched cages or alternative systems (barn, aviary, free-range, organic). Egg marking and trade are governed by EU regulations on marketing standards for eggs. Poland implements all this through its own regulations of the Minister of Agriculture and through acts. Oversight rests with the Veterinary Inspection, and registrations are run by the agricultural agency (ARiMR).
Where do you handle all this?
Three main places: ARiMR and the IRZplus system (flock holding registration and animal records), the local veterinary officer (veterinary number, welfare inspections, Salmonella testing, assigning the farming-method code used to mark eggs) and your own farm records (flock register, treatment log, welfare documentation). The IRZplus portal can be unintuitive and time-consuming, so you can send the flock status-change reports (placement, culling) yourself or let DlaFerm.pl do it — it prepares and files them to IRZplus for you automatically, if you want; the choice is yours. The law is updated from time to time — always confirm dates, forms and thresholds with ARiMR and your veterinary officer before starting production.
From registration to egg marking — what you must arrange
- 1
Register the flock holding in IRZplus (ARiMR)
The first step, even before placing hens: register the flock holding with the agricultural agency (ARiMR) and obtain a holding number in the IRZplus system. This underpins all later records — without it you cannot register placements or mortality. From registration you also keep a flock register (placement date, number of hens, origin, mortality, culling). The step-by-step is in the guide on flock records in IRZplus.
- 2
Obtain a veterinary number and approval for the holding
As an operator in the food chain, a laying farm must be notified to the local veterinary officer and — depending on scale and type of activity — registered or approved, with a veterinary number (establishment identifier). This stage also assigns the code identifying the farm and farming method that goes onto the eggshell. The number identifies the farm in trade and is required by packing centres and egg buyers. The procedure is in the guide on farm veterinary number — registration.
- 3
Meet welfare requirements under Directive 1999/74/EC
Choose and run a legal housing system: enriched cages (with a nest, perch, litter and claw-shortening area, and a larger area per bird than the former cages) or an alternative system — barn, aviary, free-range or organic. Directive 1999/74/EC sets minimum standards: area, nests, perches, access to feed and water. Conventional (battery) cages have been banned in the EU since 2012. The differences between systems are explained in the guide on cage, barn and aviary systems, and programmes and subsidies in poultry welfare — subsidies.
- 4
Mark eggs with the farming method and farm number
Every table egg (Grade A) must carry a producer code whose first digit marks the farming method: 0 = organic, 1 = free-range, 2 = barn, 3 = cages. The country code (PL) and the farm identifier follow. This marking is mandatory and must match the actual housing system — a mismatch is a serious breach. Egg grades and packing are governed by the EU marketing standards regulation. How the system affects costs and revenue is covered in the guide on profitability of laying hen farming.
- 5
Carry out Salmonella testing
Laying flocks are covered by the national programme to control Salmonella serotypes (mainly Salmonella Enteritidis and Salmonella Typhimurium). Throughout the egg-production cycle samples are taken periodically (e.g. faeces samples or litter swabs) and tested — a positive result for the serotypes covered means a ban on placing the eggs on the market as table eggs and mandatory measures (eggs sent for processing after heat treatment or for disposal, decisions on the flock). Sampling dates and duties are in the guide on Salmonella on a poultry farm.
- 6
Keep treatment records and watch the egg withdrawal period
Every medicine given (especially antibiotics) goes into the treatment log, and for layers the egg withdrawal period is especially important — the time during which eggs may not be placed on the table-egg market after a medicine has been given. Failing to observe it risks residues in the eggs. Details are in: treatment records and withdrawal periods and withdrawal periods in poultry.
The most important rules for layers
Four pillars on which legal laying hen farming rests. Act names and markings are given as a reference — confirm the legal position with your veterinary officer and ARiMR*.
Directive 1999/74/EC — laying hen welfare
Council Directive 1999/74/EC lays down minimum standards for the protection of laying hens. Since 2012 it bans conventional (battery) cages in the EU and allows only enriched cages (with a nest, perch, litter and a larger area per bird than the former cages) or alternative systems (barn, aviary, free-range, organic). Implemented in Poland by a regulation of the Minister of Agriculture.
IRZplus / ARiMR — flock holding registration
The Animal Identification and Registration System (IRZplus) run by ARiMR. Duty to register the flock holding and obtain a number before placing hens, keep a flock register and report events. Basis: the act on the animal identification and registration system.
Egg marking 0/1/2/3 and marketing standards
EU regulations on marketing standards for eggs set the producer code on the shell: the first digit is the farming method (0 organic, 1 free-range, 2 barn, 3 cages), followed by the country code and farm number. They also cover egg grades (A — table eggs, B — for processing), weight grading and packing. The code must match the actual housing system.
National Salmonella control programme — layers
The programme covers mandatory testing of laying flocks for Salmonella Enteritidis and Salmonella Typhimurium (and related serotypes covered). Samples are taken periodically during the production cycle; a positive result for covered serotypes means a ban on marketing the eggs as table eggs and mandatory measures. Basis: EU rules and the national programme.
The most common formal shortcomings
These slip-ups recur at inspections — worth knowing before the veterinary officer visits.
Placing hens before registering the flock holding
The birds are already on the farm, but the IRZplus holding number has not been issued yet. Registration is done before placement, not after — otherwise you cannot register the placement on time and a gap appears in the flock register. How to handle it is in the guide on flock records in IRZplus.
Egg code not matching the actual farming system
Eggs are marked “1” (free-range) or “2” (barn), but the actual housing conditions do not support it. The first digit must match the real system — misleading the consumer about the farming method is a serious breach of marketing standards. System differences are explained in cage, barn and aviary systems.
Not observing the egg withdrawal period after treatment
The flock received a medicine, but eggs reached the table-egg market before the withdrawal period ended. This risks residues in the eggs and is a serious breach. The withdrawal period is counted from the last dose and recorded in the log — details in treatment records and withdrawal periods and withdrawal periods in poultry.
No reaction to a positive Salmonella result
A positive result for a serotype covered by the programme means a ban on marketing the eggs as table eggs and mandatory measures — continuing to sell “as usual” is a breach. The programme and procedure are covered in Salmonella on a poultry farm.
Frequently asked questions about laying hen farming rules
Can I keep laying hens in cages?add
Conventional (battery) cages have been banned in the EU since 2012. Only enriched cages — with a nest, perch, litter and a larger area per bird than the former cages — or alternative systems (barn, aviary, free-range, organic) are allowed. Eggs from enriched cages are marked with the digit “3”. The differences are explained in the guide on cage, barn and aviary systems. This is an informational guide, not binding advice.
What do the digits 0, 1, 2, 3 on an egg mean?add
The first digit of the code on the shell is the farming method: 0 = organic, 1 = free-range, 2 = barn, 3 = cages (enriched). The country code (PL) and the farm identifier follow. The code must match the actual housing system — a duty under the EU marketing standards for eggs.
Do I have to register a laying flock?add
Yes. The flock holding is registered with ARiMR in the IRZplus system, usually before placing hens, with a holding number issued. You also keep a flock register. We cover this step by step in the guide on flock records in IRZplus.
Does a laying farm need a veterinary number?add
Yes — as an operator in the food chain the farm must be notified to the local veterinary officer and, depending on scale and type of activity, registered or approved with a veterinary number. This stage also assigns the farm code that goes onto the egg. The procedure is in the guide on farm veterinary number — registration.
What happens if a Salmonella test comes back positive?add
A positive result for a serotype covered by the national programme (mainly Salmonella Enteritidis and Typhimurium) means a ban on placing the eggs on the market as table eggs and mandatory measures — eggs may be sent for processing after heat treatment or for disposal, and decisions are taken on the flock. The procedure and testing dates are in the guide on Salmonella on a poultry farm.
Is this binding legal advice?add
No. This page is an informational guide — it organises duties and points to the details, but it does not replace the regulations or an authority decision. The law is updated from time to time (forms, deadlines and thresholds change), so always confirm key points with your local veterinary officer and ARiMR before starting production.
