Except that dogs spent thousands of years being domesticated and trained to live inside with people. Chickens haven’t. They’re still used to living outside and scratching/foraging and doing chickeny things.Why dont we compare dogs to their ancestors too shall we? Wolves spend their days wandering through the woods hunting in a pack. Something that modern dogs do not get to do. Wolves also dig dens to give birth in. Again something modern dogs are unable to do. I dont know what your trying to convince me here but it aint working
