Duck ramp and height of duck house

[HennyPenny44]

That is about the size of the door in my son's duck coop that was originally a tractor. His three pekins go in and out all day for food. They sometimes go in on their own at night but more often than not prefer to wait at the garden gate for him to appear!

We must’ve read the same article perhaps because I got those measurements from a website. As long as they go in, that’s what matters!
