Last Friday coyotes decimated our small flock, leaving only one roo.  A RIR who is almost a year old.  He's a good roo, very smart.  He was lightly injured but is doing fine.  
My question is this: I have juveniles that need to go into the big pen. I don't want to boot him out and put him by himself, but I don't know what he might do. With the hens there there was always a time of getting used to one another but they weren't usually vicious. He seems very agitated now when anyone or thing besides myself or son comes near now. I was hoping he'd gratefully accept more to protect but know that's probably wishful thinking. With him being the only one in the pen now, does that affect how I should integrate? Or should I even try?
