I have hens and rooster, i recently got a very nice pretty rooster and my other rooster keeps picking at his tail feathers so he is looking really rough right now. I have only fed layer feed but starting to wonder if I can just mix my feeds, for example I would like to mix in some feather fixer into the layer feed for my rooster. Also when my chicks are big enough to join the group i was hoping to feed a mix of layer and chick starter. Is this a bad idea or is there something else I can do? They live in a huge barn so if need be i can close off a section for the chicks but not sure what to do about my pretty rooster.
