is there such a thing my friend was asking about them??? if so how do they work and where do you get them from i hope they weren't taking the mick or I'm going to look rather silly ::) ::)
Do you mean popholes?
Some chickenhouses have doors for people and little doors (popholes) for the chickens.
i mean the little doors that the chickens come out of i thought they were called pop ups but maybe every one calls them something differant my dad calls it a slide
This link shows a pophole on the outside of the hen house,

I have one that goes on the inside of my hen house which leads into the run. It is just a hole in the shed with wood pieces attached to the upright supports and a piece of wood cut to fit that goes up and down. I have a piece of string attached and held open via a screw to hang the string on.
You can buy solar power ones which open and close via the sun light. I just cannot think what their called. sorry
