I am very interested in getting an automatic door, but when I priced the chicken specific, WOW! My coops built from all recycled material basically, and I didn't know they were that expensive. Has anyone made an automatic door themselves? Or have any ideas on what to do? I dont *need* one, but I have a 7 month old son, and some times I don't get out to the coop to let them out until well after the sun is up.
