Well the first day we brought home our pullets my dog decided to eat chicken poo. He got so sick and it went through him like mud and messed our whole house up. My wife almost made me get rid of the chickens that do. Now they have to stay in their run and chicken coop and are not allowed to wander around the backyard like I was hoping. Do you think this would happen again if I let them out? Is it harmful for my dog to eat chicken poo? Sad but true...
