Regarding my grey girl and the bullying. Here's what I've done: For the flock, protein levels good, calcium available, diet is up to par. When I'm around, I establish my dominance and "peck" the bullies when they go after grey girl, or anything else. Occasionally I've waited until dusk and then put grey girl in the roost, flicked down any aggressive advances towards her till everyone settles (I don't do this often as I have humans to attend to at dusk...). I just discovered that she's been sleeping alone in the run. Have separated bully from bullied for several days, a few times, with no change in behavior. Is there anything I'm missing? Oh, I did check for poultry ticks last night, in case irritation was causing all the bullying. No ticks, but I'll check again for the next few nights. Anything I'm missing in dealing with the bully/bullied?
The hens were all raised together...the bullying started when grey raised this last batch of meaties. Grey girl is a bantam, the other hens are full-sized. Would it help if I got another bantam or two? Or is it best if I rehomed the little one? I really can't let the situation work itself out...it's been weeks and weeks and she's losing weight.
Separated means separated - as in separate living quarters, separate runs, or alternating times out in the run. If they are kept together the bullying will continue. You could eat the worst bully and see if that changes the dynamics.
