Hi, We had a flock of 5 chickens then a raccoon killed the top hen. Now we have 4 wyandottes and one RIR. One of the wyandottes assumed the top hen spot and is really mean to the RIR to the point of injury and will not allow her to food and water. Have tried segregating the mean hen but it doesn't seem to help at all. So I want to rehome this chicken. A friend suggested we trade hens. The RIR and other two wyandottes are pretty docile and sweet birds. This plan seems like a good idea, but will it work to introduce a new hen or create more trouble in the flock?? Appreciate any thoughts or suggestions.
