It's a little tough to tell in this photo. The run door is to the right. It's just a 2x4 frame with corner support's and hardware cloth attached. Sturdy hinges as well. There is also a hasp for a pad lock.
Ours looks a lot like Baymen Moe's. Our only regret, - make the door a little higher (we'll be digging out some of the dirt in front of the door this summer). It swings out, and despite shoveling, snow and ice build-up is bad. I can open the run door only enough to squeeze in there! Glad spring is coming soon!
The inside door for the coop is same as everyone. I put a 2x6 scrap board along the bottom of the wall, tall way so there is a 6" step. I built the door to flush with that, so there is no getting litter jammed into it. When I clean it out, I'll have to park the wheel barrow outside the door, but that's ok.
It's not a great picture of the run door since I was taking a pic of the coop, but you get the idea. My door frame looks pretty much exactly like Baymen's except that I have a 2x4 cross piece across the middle for added support.
