For about one month now I have been dealing with bad behavior from one of my Ameracauna hens. We have a total of five and have never had a problem like this. This is beyond bullying, it is as if she wants to kill one of my Rhode Island Reds. I started by isolating Buffy (the victim) as I thought maybe she was ill. Her poop was definitely not normal and both chickens had stopped laying eggs. I kept her isolated for almost 2 weeks and upon returning her to the group the attacks from Cadbury (bully) were worse. I then removed Cadbury and would periodically try meetings as long as I was present to watch. Each and every time it ends the same. Buffy will immediately run from Cadbury and then there would be an attack, not pecking...a full on grab her by the neck and pin her down. I stopped putting them together at all for awhile and only reintroduced them at night in the coop and they seem to do okay but Buffy at times will opt to sleep away from the rest in a nest box rather than on the roost. As soon as morning comes it's the same thing and I remove the bully right away. I feel letting the "work it out" will result in Buffy's death. Her comb has become bloody and she appears to be losing a lot of feathers from the vicious attacks. I feel I have tried everything and if it keeps going it will not end well for poor Buffy. In a couple of weeks we will be introducing new chicks to our existing flock and I want to have this problem under control before that takes place. If anyone has any advice or past experiences with this problem I would love to hear from you. Suggestions or sharing of your stories please! I am completely frustrated and feel the only solution is to remove Cadbury permanently. If so, would the best option be to offer her to someone else so that she has to establish pecking order within a new group? We don't want to have to deal with culling her if possible.
