Of my 4 ten month old pullets, 2 of them are looking rough and losing a lot of feathers around the neck and tail, mostly. I didn't think they would moult this winter. Is that the most likely explanation, or should I be watching for something else? They haven't been laying for a month and a half, since I haven't supplemented their light or heat. So I can't use that as an indicator. Their coop is insulated, but It's been -15 to -20 C average lately, with about 8 hours of daylight. (during which I am mostly at work, so not really able to observe their behavior). I wasn't able to get a photo before they went in or the night, but I'll try tomorrow. Any ideas of what the cause might be, or what I should do to help them out? I feel like they must be really missing those feathers right about now!
