Hi! I just recently acquired a Leghorn from a friend of mine. I have an existing flock of 2 ISA Browns (5 months) and an oversize Polish bantam and an undersized white unknown rooster. I've kept the Leghorn and my flock separate for 4 days now, but they have access to each other and are only separated by chicken wire. This morning I tried integrating the birds together. The Polish roo tried to mate with the Leghorn, but other than that the roos left her alone. The ISA Browns on the other hand relentlessly pecked the Leghorn. All the Leghorn can do was to run away, but then the Browns would just grab her by the comb or neck feathers. Eventually the Leghorn sat down and the Browns sat on top of her, but about 5 minutes later the pecking and harassing just continued again. The Leghorn at this point is bleeding all over the comb, and she is not fighting back. Please help me as I don't know what to do in this point!
