I have had large groups of chickens in my past when I lived in Colorado. I let them go when I moved to NE TX. Back in August, I purchased 5 pullets; 2 BOs and 3 RIRs. In my past experience, BO's are very laid back and RIRs can be rather vicious. Not this time... They all started laying about early November. there were no issues and they all got along.
About two weeks ago I noticed a bald spot (feather picking) developing at the tail head of one of the RIRs. The next day I went out and there was a bare spot, meat missing, blood and a 2nd RIR had also been balded at the tail base but no broken skin, just irritation. I pulled the injured one and blukoted both.
Long story short. I sat in their area and watched to see and it was both BO's that were doing the picking/eating. But they in turn got the RIRs involved doing it as well, to the other RIRs. I had to put down the worst damaged ~3 days ago. I separated the BO's out and put the 2 injured RIR's together. (The BO's don't attack each other) They (RIRs) were OK for 2 days. Tonight I found one of the RIR's ate the whole back end out of the other. I put that one down a short while ago.
I have now put the 2 BOs back in the pen along with the one remaining (Blukoted, healing) RIR. I anticipate that at some point tomorrow, I will be euthanizing the final RIR and will be down to 2 chickens.
