Layer feeding plan phase by phase
A laying hen needs a different feed at different points in the cycle. From rearing, through pre-lay feed, peak production and on to late lay, the density of nutrients shifts — calcium, protein and energy above all. We explain how to build a phase-feeding plan that follows the flock’s age and lay curve, not just the calendar.

A layer feeding plan isn’t one feed for the whole cycle but several phases matched to the bird’s age and stage of lay. A pullet in rearing is fed one way, a hen just before her first egg another, and a flock at peak or end of lay differently again. Each phase has its own nutrient density, because the bird’s needs, its feed intake and its shell quality all change. A well-built plan simply follows those changes.
Why does phase feeding make sense?
A hen’s needs aren’t constant. A young layer at peak production lays almost daily and needs plenty of protein and amino acids. As she ages, lay and feed intake shift and the shell grows weaker, so the demand for calcium rises. Feeding one feed for the whole cycle would leave the bird overfed at one stage and short of a key nutrient at another. Phase feeding lets you give exactly what’s needed at each stage — without waste and without gaps.
Feeding phases from rearing to late lay
The plan runs from rearing feeds, through a pre-lay feed, into successive lay phases. In later phases calcium usually rises, while protein and energy are matched to lay and feed intake.
Rearing: starter, grower, developer
Before a hen starts to lay she goes through rearing feeds: a starter for the youngest, then a grower and a developer. Their job is to build a well-developed, even frame and body weight at the right time. This is the foundation of later lay — a hen that enters production poorly prepared finds it harder to hold condition and egg quality across the cycle.
Pre-lay feed and the calcium reserve
A couple of weeks before the first egg, a pre-lay feed with raised calcium is given. It helps build a calcium reserve in the spongy (medullary) bone, which the bird draws on when forming the shell. It’s a short but important bridging phase between rearing and full lay — it prepares the hen for the rising demand for calcium.
Phase 1 — peak production
At peak production the hen lays the most, so the feed carries the highest density of protein, amino acids and energy. This is the moment when well-covered needs translate into the number and quality of eggs. Shortfalls in this phase are the hardest to make up later, which is why the peak feed is the most nutrient-dense of the whole cycle.
Phase 2 — mid lay
After the peak, lay slowly drops and the bird eats a little differently. The mid-phase feed has slightly lower protein and energy than the peak feed, but usually higher calcium. The point is not to overfeed the flock with nutrients it now needs less of, while starting to support the weakening shell.
Phase 3 — late lay and calcium
Towards the end of the cycle the shell naturally deteriorates, so the late-lay feed carries the most calcium — often partly as coarse, larger-particle limestone. The coarser fraction stays in the gut longer and releases calcium at night, when the shell is being formed. Protein and energy are matched to the lower lay and feed intake.
Feed follows intake, not just the percentage
What counts is how much of a nutrient the bird eats per day, not the percentage in the feed alone. When hens eat less — in hot weather or on a more energy-dense feed — the mix has to be concentrated so the daily intake of protein, amino acids and calcium stays full. That’s why a feeding plan is always read together with actual feed intake.
Phase-feeding plan step by step
- 1
Start from the guide for your hybrid
Every layer hybrid has its own management guide with recommended phases, nutrient densities and body-weight targets. Start there — it’s your reference point. Build the plan around the specific hybrid you keep in the house, not around generic, averaged tables from a different cross.
- 2
Set phases by age and stage of lay
Lay out the cycle in phases: rearing (starter, grower, developer), a pre-lay feed, then successive lay phases. Tie the phase boundaries to the bird’s age and stage of lay, not just to a round number of weeks. That way every feed change lands on a real change in the flock’s needs.
- 3
Bring in pre-lay feed before the first egg
A couple of weeks before the expected first egg, switch to a pre-lay feed with raised calcium. This is what builds the calcium reserve before lay. Don’t skip this phase or cut it too short — it’s preparation that pays off in shell quality at the start of lay.
- 4
Raise calcium as the flock ages
Plan for calcium to rise across later phases, with part of it given as a coarser limestone fraction in late lay. This answers the shell that weakens with age. Protein and energy you tend to lower over this time, matching them to the lower lay and the changed feed intake.
- 5
Match density to feed intake
Regularly check how much feed the flock actually eats, and count nutrient intake in grams per bird, not just the percentage in the feed. When intake falls — for example in hot weather — concentrate the mix so the daily ration of protein, amino acids and calcium stays full. The plan should follow real intake.
- 6
Change feed gradually and note the results
Make the transitions between phases gentle, mixing old and new feed over a few days so intake isn’t disrupted. Watch for even mixing and a consistent feed form. Note lay, intake and shell quality at each change — that way you’ll see whether the plan is following your flock’s lay curve.
Frequently asked questions about the layer feeding plan
Why split layer feeding into phases?add
Because a hen’s needs change across the cycle. At peak production the bird needs plenty of protein and energy, and towards the end — above all more calcium, because the shell weakens. One feed for the whole cycle either overfeeds or fails to cover needs in a key nutrient. Phase feeding lets you give exactly what the flock needs at each stage.
What is pre-lay feed for?add
Pre-lay feed, given a couple of weeks before the first egg, has raised calcium. It helps build a calcium reserve in the spongy bone, which the bird draws on when forming the shell. It’s a bridging phase between rearing and lay that prepares the hen for the rising demand for calcium and supports shell quality at the start.
Why is more calcium given in late lay?add
As hens age the shell naturally deteriorates, so the late-lay diet carries more calcium — often partly as a coarser, larger-particle limestone. The coarser grain stays in the gut longer and releases calcium at night, when the shell is being formed. This helps hold egg quality in an older flock.
Do I set the feeding plan by the calendar?add
The calendar is only a starting point. Tie phases to the bird’s age, stage of lay and actual feed intake, and the whole thing to the guide for your hybrid. When the flock eats less, the mix has to be concentrated so daily nutrient intake stays full. The plan should follow the lay curve and intake, not just the number of weeks.
