well, i haven't built a coop yet.... i guess i am still in the "planning" stages. but i was going to build one with wheels that way i can move it to the front in the winter where i get almost full day sun. and it will either be insulated, or double walled. my yard is fenced with a 4 foot high chain link, and i was planning to let the little girls just free range on my property. but i do have hawks in my area. so i was hoping they would be smart enough to hide when the hawk is near, like the wild birds do. and i also am wondering if the fence will be adequate to keep them contained in my yard, and not my neighbors. thanks
