well, their coop is about 25 sq. feet on the ground, and about four feet high, so pretty small. I cannot let them free range because of our dog, cats, and the fact we live in the desert and i think they could get over our wall and get caught by coyotes. My rooster will peck my feet sometimes, but if you pick him up or even touch him he calms right down. are the hens prone to fighting, and would they be in trouble if my big ameracuana stepped on them? would i need more than one hen? would my silkie mate with them and would the eggs be viable?
