Hello all, I raise my chickens in a suburban environment, I have almost 1/4 of an acre in downtown Novato, CA area, and though I have always had field rats, they are getting excessive. They eat up any misc chicken feed scattered on the ground. I have considered putting up an owl house, but owls can kill chickens as well. Or can they. I dont breed because Im not allowed to have a rooster- so I buy 5 month old pullets. Any suggestions? Perhaps there is a small owl I could try and attract? I dont have a cats, but there are plenty of feral cats in the neighborhood that come around. Still does not take care of the rats. Help!
