the neighbors dogs got into the chicken coop and now I have 2 chickens that are heart, one just has a lot of feathers pulled out of her the other one's tail feathers are gone and most of her feathers are gone I have them in a pen inside the house I just don't know what I can do to help them get better they have food and water in the pen with some feather grower pellets in the pen. I hope that helps them. I will post pic of them hopefully in a little bit. Im just worried about them I hope they will get better! how long does it take for a chickens feathers to grow back and how long does it take for tail feathers to grow back?
