Our neighbor gave us 1 chicken since it's buddies died (2 ducks). Our 7 chickens have always gotten along, now with the new chicken, I noticed that it's comb looks like it has been pecked, along with the feathers on its head. I did not realize that we needed to separate them at first. What do we do now? Keep them separate and then only integrate them when we are watching? Or is it too late? Thanks. also any ideas on keeping them off the deck. I shew them off when ever I can. They especially like the deck when I am out there grilling meat.
