First stab at a coop design..

[Al Capon]

Don't know if other people agree but the ramp down appears to end right up against the fencing. I had something like that but it caused a traffic jam in the mornings. I ended up making a L shaped ramp down to more open space and it's funny because now the march straight down in a line.

Ha,.goofy chickens. I've been guessing at my ramp size,angle,etc.. I don't know if a chicken has qualms about traversing a course on their way to the floor.

Changes can be made, nothing is set in stone yet.

No. My girls love their natural lighting. I have 3 windows and full size people door glass, all thermopane. One of the windows is actually framed so that the bottom of the window shines directly into 3 nest boxes. (the boxes at the top are open to the window, with a hinged roof over the boxes. The top of the hinged nest cover bisects the window.) The girls love those nice bright nest boxes!

I was afraid to, but I can't throw a couple windows in it, no problem, that would definitely aid in Summer cooling.

A point to reinforce is that light actually encourages egg laying. I have windows galore. The chickens enjoy big windows as much as we do. If they let in direct sunlight, you'll see chickens sunbathing where the sun rays fall. Chickens need direct sunlight to absorb vitamin D through their feathers much as we do through our skin.
