I have 5 6month old birds, 4 sex links & 1 barred rock. I recently got 3 18wk old sex links. I breeder told me that I should just put them in the coop with the others and let them work it out. Well, that ended with 1 of the new birds being beaten pretty bad & the other 2 constantly harrassed. I've since separated them to one end of the run so the others can see them. Will my original birds ever accept them or should I start looking for a new home for them?
