When do chickens moult?
Chicks go through one complete and three partial moults during its growth to point of lay at about 8 months old, after which the mature bird normally undergoes one complete moult a year, usually in autumn although this depends on the time of the year at which the bird started laying. Generally complete moulting occurs from 1-6 weeks and partial moulting at 7-9 weeks, 12-16 weeks and 20-22 weeks, and during this latter moult the stiff tail feathers are grown.
