One small step for man, one giant leap for chickens

Oh, larger than I thought.

I find it intriguing and would like to see more pics from different angles to see how it is supported.
A pic of the inside might help to figure out why they aren't going in.

But back to your question....are your birds young?
I believe you said you recently acquired them and it could just be that they are not used to the new environment.
Chickens take some time to get used to new things, so I'd suggest just keep putting them in there and eventually they will probably figure it out.

I too would like to see more photos, I'm just intrigued myself.

It basically sits atop the trunk of a tree I cut. Was going to set a post in the ground, but the tree happened to be exactly where I wanted the coop. The top of the stump is cut into a rectangle shape, about 200x200mm (5x5"). Two support beams under the centre of the coop are set 200mm apart so it fits snug over the top of the stump. Then two threaded rods go through the beams and through the square top of the trunk and are secured with bolts on either side. I'll get some pics and post
