I'm having trouble coming up with an adequate latch for my coop's human door. It's a wood converted playhouse, and the door is mounted on the outside, so that it's not flush with the doorjamb. It sticks out about 1 3/4 inches. Plus the door - there are upper and lower windows in it - and the frame are kinda narrow.
What kind of latch can I use that's pred-proof, but doesn't have to lie flat? Right now I have 2 hook-and-eyes, with the little springy-pullback things. I know this isn't raccoon proof, so for the time being, I am wedging a 2 x 4 between the bottom of the door and the edge of the "porch".
Any suggestions?
Thanks!
BTW This will be my gals' first night out!
