How big do the chickens have to be before a cat won't mess with them, OR will that ever happen? I have a great cat, but she is a hunter. I get up to 5 good morning treats in my garage daily (gag). I know given the chance, she'd take out a chicken in a heart beat. She is pretty small, so when they get real big will she mess with them? I am fixing to put them in their intermediate brooder outside (they are 8 weeks old) and I am getting so worried now that there is a real possibility of losing one since they will be out in the real world sniff sniff sniff. They have been in my garage and their baby brooder is tight as a drum, but she watches them like a hawk.
