What automatic door fits a Producer’s Pride Sentinel chicken coop

[Dmoore11215]

I have a Sentinel chicken coop and new to chickens. The door dimensions are 12” wide x 15.9” long. I cannot find a door that fits and not too expensive

Producer's Pride Sentinel coop, correct? All the ones I've seen have a small run attached to them and is for the most part, secure. There is no need for an auto door on this setup IMO unless it's being installed on the run to let them free-range or go into another run. The better investment is to add hardware cloth bottom perimeter and anti-dig skirt, to beef up security if you haven't done that already. Also ventilation, those things look very restrictive to airflow
