I live in the northeast, where the weather is now cold, and I am concerned about my 2.5 year old buff chantecler who rather suddenly lost many of her feathers about a month ago. Her head and neck feathers are growing in slowly but surely. Some of her wing feathers never fell out, so those remain. However, most of her breast, much of her back, and both her thighs are bald. In those areas, there are some tiny little nubbins coming in, but most feathers seem to be arrested in development before fluffing out. The coop is not heated, but is well insulated. Her behavior has been pretty good for a molting hen. Sometimes molters seem to prefer the solitude of the coop when I open the door for "recess" in the afternoon, but this one has been fairly active, staying with the flock most of the time...until this past couple of days. Temp has been in 30s during day, and in 20's at night. Yesterday and today, she appears to be struggling - hanging back away from the flock, sometimes shivering. This is not unusual for what I've seen of molters, though. It's just new behavior for her. And, without her feathers growing at any appreciable rate, and the winter only beginning, I worry that she will not make it through the winter. I watch and make sure I see her eating and drinking everyday. And she is. Droppings appear within normal limits. She has been sleeping in a nestbox at night, to keep warmer, I assume. She and the other 16 chickens get layer pellets, a few cups of scratch grains mixed with birdseed (which is rich in nuts and sunflower seeds) each day, whatever they scavenge from the compost bins, and whatever they forage from the yard and garden (when there is not snow covering it). She is in the mid-lower end of the peck order, but definitely not at the bottom. There is one hen which occasionally pecks her tail area, but I have not seen anyone peck at any other part of her body, so I do not think cannibalism is contributing much to this, if at all. Last year her molting pattern was totally different - She lost only a few feathers at a time, so that you could hardly tell she was molting. Two of other hens (barred rocks) started molting later than this hen, and are now almost totally done, with nice warm feathers growing quickly. While I have had other hens undergo full molts, none have gone so slowly as this one. Is this within the realm of normal molting? If there is something wrong with her, what might it be? Is there anything I can do to encourage faster feather growth?
