Today I mixed the last of my chickens back together. Diesel (my black orp rooster) and his hens were opened up to the rest of the flock. The hens actually had a harder time mixing in than the roosters did. The head rooster in charge is a Buff Orp and he buffaloed Diesel quickly despite weighing 5 pounds less. I was watching carefully to make sure there were no extremely violent actions but it went quite well. I think one reason I have had good luck integrating everyone is because each group has it's own space it can retreat to while they are acclimating to each other. Now I have a lot less feeders and waterers to worry about all winter. I needed Diesel's pen available because I plan on putting quail in there soon.
