Hi, all, I am new to backyard chickening. My fiance raised them for years in upstate New York. We are in Central Texas now, where the greatest non-bird predator is definitely going to be coyote. Our thought is to put a couple layers of concrete block underground as a base for the walls of our coop. How deep will a coyote (or other predators) dig to get under a fence and into a coop? Any other thoughts about this plan?! THANK YOU for your help! We're very excited about out chickies (10 days old today)!
