OK, so, I've got 3 baby cornish cross mixed in with my layers. It hadn't occurred to me that the chick crumble they were eating would be bad for them. Unfortunately, I only have chick crumble and turkey food. Can I mix them half and half to get something more appropriate for their needs? I can put them in an aquarium INSIDE their brooder to give them their own broiler food there. Would that help them grow better?
