used a cutting board for the door, it opens and shuts from the inside and a latch to lock it at night.Fluffy butts were helping and are already using it.
Nice job - very creative on thinking of a cutting board to use! Do you have a locking mechanism in place to prevent a raccoon from prying it up to gain entry?
Yup, the lock is a pin which goes into the side of the wood fram and into the cutting board. A Raccon would have to get into the fenced run to get to pop door and the door opens from inside the coop. I was surprised how easy it was to make. Hubby made a recessed rail pretty easy on his grinder.
If the bottom of the door is nested in the frame, it seems unlikely that the door could be opened from the outside. There would be no part to hold to pull the door open.
