What actually changes when laying slows
A layer ration is engineered for a hen in full production: generous calcium for shell-making in every mouthful, and protein pitched at the demands of turning feed into eggs day after day. A senior hen who lays once or twice a week, or has stopped for the season, is no longer running that factory. She is still using calcium — for the eggs she does lay, and for her bones — but she no longer needs it forced on her at laying strength in every bite, and excess calcium in a non-laying bird is a burden her body has to process rather than a benefit. What she needs undiminished is condition: enough protein and energy to maintain her body, renew feathers, and keep her reserves through cold weather and moult.
Calcium on demand, not in every bite
The standard, sensible arrangement is a two-part one. Her main feed becomes a plainer ration — a grower-style or all-flock style feed with moderate calcium and solid protein — and calcium moves to a separate small pot of oyster shell or limestone grit beside the feeder. Hens are remarkably good at self-selecting calcium: a bird who needs it for a forming shell will visit the shell pot with purpose, and one who does not will leave it alone. Keep the pot topped up and dry, and watch it as a rough gauge — heavy use suggests laying is more active than you thought; a full pot week after week confirms the slowdown. Ordinary grit for the gizzard stays available as always, in its own right.
Protecting her condition, not just her ration
Changing the bag is only half the adjustment, because senior hens often lose out socially before they lose out nutritionally. Check that she actually eats: younger, pushier birds can shoulder an old hen off a single feeder, so add a second feeding point or feed her separately for a few minutes if she is being displaced. Then check the hen herself, monthly, in your hands. The keel bone running down her breast should feel covered — you can find it with your fingers, but it should not stand out like the edge of a ruler with hollow muscle either side. Sharp keel: more feed access and a review of what she is eating. Plump and heavy around the abdomen: ease back on the starchy treats and scratch, which fatten an old bird without feeding her properly. A hen who is off her food, hunched, or dropping condition despite eating well needs a vet's eye rather than another feed change.
Whoever feeds her, feeds her the same
In most backyard flocks the senior hen's new arrangement fails through kindness rather than neglect: one person pellets her from the new bag while another, remembering the old routine, tops her up with layer feed and a generous hand of corn. The two-part system only works if every feeder knows which bag is hers and that the shell pot is a fixture, not an optional extra. That is a small care plan, and KinsLe's Care Teams holds it as shared duties — her ration, the shell-pot check, and the monthly keel check written down where everyone who feeds the flock can follow them, so the old hen's careful new diet survives the weekend helper.
