I got some hens months ago that look a little rough, they must have been with a over active roo. These girls have been debecked and they were only being feed corn. They are really nice girls, I have been feeding them 20% laying crumbles, they get some BOSS, I also have been giving rooster booster vitamins, they also get yougurt. What else can I give them with more protein cat food is very hard for them to eat because they have been debecked. I was just hoping they would be looking better by now. I have checked them for bugs, and see nothing. I just wish they would grow feathers back. Poor girls look bad enough without beaks, wish they had wonderful feathers to make up for it. Just wondering what I could do to help them out?
