Hi all. I'm after some advice please. I have a cockerel who hatched in August last year. Until recently, he's lived harmoniously with two hens hatched with him, 2 a year older and the 2 old ladies who are about 4. A few weeks ago, one of the old girls started taking herself to bed by herself in the 'emergency' coop we have, then we noticed her running away from the cockerel whenever he came near her. She's still been going round the garden with the other girls, just been trying to keep away from him. Today, we've noticed she's got some wounds on the back of her neck - some of them look quite nasty. She's fine in herself, eating and scratching about and has laid today. We're assuming the wounds are from the cockerel as none of the others seem to be bothering with her. We've been trying to rehome him for a while now and, typically, someone has now been in touch to say he'll take him. I'm now worried that he's turning aggressive (there's been no sign of aggression towards anyone other than this one hen) and don't want to pass on a problem bird to anyone. What I really want to know is - is aggression towards just one hen normal? Is it likely to stop or just get worse? Is there anything we can do to help the situation? Or should we be considering dispatching him now? Thanks for any advice.
