I have 2, 4 1/2 month old BO roos that are now in with the 2 big girls,(1 year old),and 7 other 4 month old pullets. I want one of these two roos to be the new man of the flock. One of the BO hens is really, really bossy. She isn't beating up on the babies but, when she walks in the coop, everyone scatters and lets her eat, dust bathe and pick her spot on the roost. The roos are terrified of her. I want babies in a few months and that does require that the boys get closer than 3 feet. Should I pull her out of the flock for awhile to let them grow up or will testosterone take care of things? Neither roo has crowed yet but they are pretty sizable, almost as big as the grumpy hen.
