I got my first chickens last spring and this has been my first winter with them. It was a rough winter but everyone made it through just fine. I have a question. I have 6 hens and have noticed that a couple of them have had their feathers picked out back by there tail right above the vent. Have read that it can be caused from boredom and because of the hard winter. I just started them on Feather Fixer for more protein and also give them black sunflower seeds and meal worms. I can't imagine it's mites as they don't free range and it's been very cold. What are your thoughts and will it get better. I plan on getting a couple of more chicks this spring and don't want to subject them to this. I have heard of peepers that you can put on your birds...don't really care to do that.
