I have four hens that have gotten pretty beaten up on their backs by my rooster. They all have a lot of serious feather loss on their backs and they are looking really red and burned. They are now separated from the rooster so they can heal and grow their feathers back. Does anyone have any suggestions on keeping their little backs from getting burned? I bought some baby t-shirts and tried to fashion some kind of covering for them but that failed! They did not like it! They have plenty of shade in their pen so I am running out of ideas. Anyone know of anything?
