My problem is that my rooster is bullying just one of the six hens I have. 4 of the six hens I have had for about 3 years & back in late July one of my girls hatched out 4 eggs, which produced 2 hens & 2 cockerels. I gave away one cockerel as he was very aggressive to the others & me. The other male is quite good natured, now 7 months old he constantly crows & performs his male duties with great enthusiasm. It's just over the last few days he seems to have taken a dislike for one of the older girls, & every time she leaves the coop he really attacks her to the extent that she won't venture over to the feeders. I've tried shooing him away from her & I have sprayed her with that purple anti pecking liquid, I even banned him from the run for a few hours, but he's just as bad. I don't really want to find new homes for either of them. Any advice would be most welcome.
