Good idea. I caught a possum in my other pen. My wife called to tell me. When i got home he was sleeping on the ground. Dont think he got any birds, but he got a .22 round to keep him asleep.
I currently have 10 or so pigeons in coop made out of a converted dog kennel. I am going to be buying 5 homers this weekend and probably 5 or so more in the next few weeks. Realistically, what size coop should I make for these birds? Is there a general rule of thumb for how much space they need...
