The First Molt: What to Expect
By Bertie Holcombe, Poultry Editor — Published 1 October 2025 · Last reviewed 15 January 2026
The first molt looks like a disaster. Feathers everywhere, production at zero, birds looking rough. This is biology, not illness.
The annual molt is triggered by shortening days in late summer and early fall. Most northern-hemisphere flocks enter molt in September or October, though individual variation is significant — some birds molt in August, others hold off until November.
Feather sequence: molting proceeds from the head backward, generally: head, neck, breast, body, wings (primary flight feathers last). This predictable sequence has practical use — a bird who has already replaced her neck and body feathers but still has ragged primaries is midway through molt and may resume production in 4-6 weeks. A bird with ragged primaries and still-dull face is early in molt.
Production during molt: most birds stop laying entirely during active molt. Some partial-production birds in early molt maintain 1-2 eggs per week. A bird in active pin-feather growth (the new feathers emerging as quill-tipped spines) is diverting protein resources from egg production to feather production — it makes biological sense that she stops laying.
Duration: standard first-year molt runs 8-12 weeks. Hard molters (birds that lose a large volume of feathers rapidly) finish faster and return to production sooner than soft molters (birds who lose feathers gradually with little appearance of ragged plumage).
Management during molt: increase protein in the ration to 18-20% during active feather growth (switch from layer pellets to flock raiser temporarily, or supplement with black oil sunflower seeds, which run 18% protein). Do not reduce feed access — birds in molt have elevated nutritional requirements. Expect egg production to resume 8-16 weeks after molt begins.
