Hey folks been awhile since I've posted here. Got a couple of hens that are getting bare butts and one really bad! The worst one has lost a lot of feathers and losing them going up onto her back now. I have sand seven dust and DE bathing areas for them. And haven't found lice. The worst one is a broiler and she roost on ground thinking it may be a rat problem. But what I need to know is a major increase in protein to help get the feathers growing back because she has to be miserable. I've heard of calf manna being a good protein bonus any info will be helpful!
