Phil, my RIR roo is only 5-6 months old. Mabe next summer he'll be enough to protect his girls. I wouldn't want him to hurt Jasper too badly though. Luckily he's a fast runner.
I would like to free range my chickens but I am sure my dog would chase them. When he gets around the yard he growls at them and looks for a way in. He got in once by mistake and chased them until I caught him and put him out. Any suggestions?
