My RIR Sussex Rachel was put out of site and out of ear shot (about a block away) from the rest of the hens for 4 days. This morning I tried to let her back in with the other 5 girls and it was as if I had dropped Satan himself into the yard all the hens were having breakfast when I put Rachel back in and they all stopped eating, they felt her presence, it was as if she never left. Can we do a chicken exorcism? Two had gone into the coop and were nestled down on their nests to lay well Rachel goes in and goes nest to nest and terrorized my girls till they left the nests and the coop. I went in they followed me back into the coop. Rachel had settled into one of the nests but decided to stand on a dividing board to stare the other two down I nudged her off she hopped back up we did this 3 times. One hen decided to leave but Rachel went for her pulled out some feathers so I snatched her up and put back out in the yard in her small area. I watched to see if the others would defend themselves against her but they did nothing so I intervened. Short of soup I do not know what else to do she is just the most hateful animal I have seen. Her sister Phoebe has calmed down a lot since Rachel has been removed. She is still somewhat aggressive but nothing compared to what she was when Rachel was in the coop. Rachel did take the place of the roo and started to mount the girls while Phoebe pecked at them. Does she think she is a rooster and this is why she behaves like this I am totally baffled. Is this normal behavior many people have said they never seen hens this mean. HELP!!!!
