Automatic chicken doors

[Rono73]

I have Toulouse Geese, Khaki Champbell ducks and chickens all living in the same coop. I need some help choosing what size door I need to allow the geese to use it.
Anyone have any issues with geese going thru an 8 x10 or 11x12 door?

Toulouse are large geese, so the larger the better. They can be trained to duck down, and I've seen mine slide in places on their bellies, but to make it easier I would get a larger door.

If you're getting an automatic door make sure the trip sensor isn't accessible or they'll likely rip it off.

Embdens for example can stand 3'

I have African geese using a 20" turkey door. Although they'll happily squeeze out half that size in the morning, I can't see them going in at night. Ducks happily put themselves to bed. 80% of the time the geese need to shooed in. They do use it on their own, but they come right back out again if it says open. And then it automatically closes locking them out and a coyote comes by.....

I got my door on Amazon but it is no longer for sale there. I know I saw turkey doors elsewhere but I can't remember where.
