I am trying to intoduce four 14wk old ee's to four 32 wk old isa browns. I've been trying for six weeks all ready and thigs are going badly. The isa browns chase them down. Today I went out to let the babies out and realized that the big chickens had pulled down the board that seperates them and it was awful. All but one of the babies have no tail feathers just bare bloddy chicken rumps. I am heartbroken. I sprayed them with this blue spray (sorry forgot the name - it's for livestock) they seem to be okay they are walking around drinking, eating etc. Do you think the problem may be that I have had them hidden behind a wood board. During the day I let the babies out into a seperate pen so they do get to see eachother, and I let them back in at night when the big chickens have already gone upstairs to roost. The babies almost always go right up the stairs and roost of the floor (not the poles) but they don't go hide in their make shift cage either. I am at a loss at this point. The baby that has no damage is definately a fiesty one, and he is the smallest so I am a wondering if the other babies are protecting her. Will the feathers grown back? Should I get some kind of see through cage for inside the coop? Is it possible that the big chickens are jealous of the extra attention that the babies get ?(I sometimes let the babies wander the yard) Sorry for all the questions. Any help would be greatly appreciated.
