Hi all-sorta new here-I was a member ages ago, and well lost my way. Ill re-intro myself at a later time. I have 2 established coops- 1 coop is 1 roo and 2 hens, the other 1 hen 1 roo. They are all about 5 years old, I've had most of them since they were babies. I acquired a lovely Rhode Island Red hen, we named her Willie she looks young but could be anywhere from 1yr-5yrs old (the previous owner wasn't sure). We kept her quarantined for a bit, and when we deemed her healthy went about introducing her to the flock. We decided since she wasn't used to free raning to put her with the larger group, since my roo is fantastic at keeping the girls out of trouble (the other rooster is lazy LOL). We put her in a cage inside the coop and it seemed to be fine- the girls were interested and there was no fighting thru the cage (the hen in the smaller coop, Dum Dum had pecked her thru the cage and given her the feathery what for). Later that evening we decided to let her out with them and see how things went. As expected they chased her a bit and pecked at her but left her alone for the most part. I was surprised that my generally docile hen, Sissy was bullying her the most-during the day. When it came time to go to sleep, Willie tried to go into the coop and she was straight up attacked by my other hen, Lily. Lily wouldn't let her into the coop. I was able to pull Lily out and let Willie in..and it was fine. The 2nd day they continued to pick at her and chase her. Last night was the worst- Lily was relentless. I tried the pulling Lily tactic again and it didn't work. At some point Willie forced her way in, and they settled. Lily doesn't really bother with Willie during the day which is odd-because Lily is a bully, she used to be pretty mellow, but since the other 2 hens in the coop passed away over the winter she's been picking on Sissy. Come to this morning-Sissy is pursuing and picking on Willie, still-and it seems more relentlessly than before. Will they ever "work it out" ? How long should I give it? Should I try her in the other coop? My rooster likes her, but he obviously is smart enough not to put himself between his ladies, though.
