Hi All, The title covers my question, but maybe a bit of background will help paint the picture. My young cockerel (1 year old) started attacking my older Australorp, to the point of creating a great big hole at the back of her neck. I initially thought this was overamorous behaviour, but now I am wondering whether it was a struggle of the pecking order. I was not around when all of this happened, so am not sure what the actual reason was. When I got back, it seemed that he had developed a taste for doing this to her, so he has been rehomed. (She has recovered and is back at the top of the pecking order). His favourite girl, Twiggy, has now become a real bully, emulating the cockerel's behaviour, including attempting to mount one of the other girls.l also introduced a new girl from a friend who was being eaten by another cockerel recently, probably not a good idea, but I felt very sorry for her. Twiggy also does really ugly 'sniper' attacks on the new girl, seemingly without provocation. She has not drawn blood yet, but feathers, newly grown, are being ripped out. I put some bad tasting liquid on her neck to try and discourage Twiggy's harrassment. But the new girl is traumatised (she did have a week's worth of getting-to-know-you before I let her out) Twiggy was always the underdog. She is now the biggest bully towards the new one, as well as to my tame guinea hen. I have put her into time-out, which consists of a wooden rabbit house and a small run, all in all about 2x1m. It is in the chicken run. So she sees all the other birds until I let them out to free range, and she sees them in the evening before bedtime. I give her something special every day (greens, bugs etc) to keep her entertained, but she seems very anxious. I hate to see her like this, but am fairly sure that if i let her out now, she will revert to her bad ways. But I am not a chicken expert, hence my posting here for advice. Short version: Should her time out setup be completely away from the other chickens? So they don't see each other? How long is long enough for time out? (She's had 4 days now, last time the 2 day timeout did not work) Has she been 'spoiled' by the cockerel, never to be a sweet chicken again? Is the timout setup too small? And, finally, the person who took her boyfriend might be willing to take her too, is that the most humane way forward?
