I have three rescue chicken, so i have no information on how old they are. Within the last few days, one of them has starting losing feathers all over the coop. It's the middle of winter, so based off of everything I'v read, this isn't a time chickens would molt, but if it were mites the other chickens would likely be affected too, right? It's mostly the feathers from under her wings that she's been losing, but her neck has some quil? (I'm not sure the term) things coming through between feathers, which is what led me to think it's molting. Any information/thoughts would be great, also, if it is molting- will he chicken be fine outside in the middle of winter without all it's feathers?
