I posted about a month or so ago about my two girls losing feathers. They are both australops, got them March of last year so they're not even a year old. They aren't losing them at skin level, it's like they are being cut off. I've dusted them 3 times now, although I haven't seen any bugs, but it continues to get worse. It first started off at their tails, but it's moving further up their backs. When I cleaned out the coop yesterday, I noticed mouse droppings. Also, my girls have always laid in their box, but today I found an egg on the ground. It didn't roll there because their box is in the top of the coop and it would have broken if it fell to the ground. Could the mice be chewing off their feathers? I haven't noticed a lot of feathers laying around, but on the other hand I know the girls will eat their own feathers. If it is the mice, how can they get so much and so far onto the birds without getting eaten themselves? I've checked all over the coop, and there's nothing they could be rubbing against that would be breaking them off. I haven't made any changes inside the coop since I got it last year. Their feathers used to be so shiny and beautiful black, now they are all broken off. I noticed today too that the breakage is moving down to their wings too. I don't think there is anything medical wrong. The eggs are still fine and production is still the same. Their skin is still whitish pink and no scabs. I haven't seen any bugs on their skin, just dirt from dirt baths. They're alert, eat and drink fine, and get to run around the yard when I'm out there. I check on them every day. Ideas? Help?
