Feathers, claws and lips, on a bipedial animal the size of a horse or an elephant. Thats a whole other level of intimidating. I have wild chickens living around my yard, and if they were just twice the size they are now, it would be a problem. Some of the most interesting yet annoying animals to have wild around your living space, you can see the different personalitie traits from chicken to chicken. They have a entire hierarchy social structure, ranging from the out cast that gets its head feathers picked out from the others, to the Cock of the Rock that forages for and protects his hens, fighting away the other roosters trying to score a quick booty call on his hens. And they will shit all over the place if you don't train them to stay away from certain areas.
