Yours is sort of like mine, I have a small feed room in front of and separate from the birds. I have to enter the bird area to get egg, which is no problem unless I trip and fall at which time my birds would devour me.
I use a heated fount so I only have to change water every couple days, I have a heated fount outside too. I mainly go into the coop to let the birds out and lock them up collecting eggs at the same time. I have thought about an timed hen door, but I kind of like the idea of being forced to go outside and open the coop or I would sit on my butt all day. I know me.
This guys coop has a foot x foot box running the whole length of the coop and you open the "box" from the outside, Which is nice but I would worry about the boxes being too cold in winter and too hot in summer not being a part of the main coop air flow.
I know I am explaining it poorly. sorry for that.
I think I know what you mean. The nest boxes are on the outside of the coop right? Yeah, I don't really know how well that would work for our winter climates. But to each his own I guess.
I have not gone with heated founts yet. I don't know how I feel about it yet so I just bring out warm water every few hours when its really cold like it has been. Water freezes up in a few hours. I don't mind going out either. i love to spend time outside watching the birds and it gets me off my buns too!
That is funny about the birds devouring you! I JUST said the same thing to my husband about the turkeys and geese cause I biffed it outside on some ice and I said it was a good thing they weren't around or I would have been a gonner for sure!!
