Internal coop ?

It all depends on how the coop is layed out.. it all needs to be located so its easy for you to get around inside to feed and water and gather eggs and clean..it doesnt really matter as long as its good for you and the birds..

 

I believe as long as you do not have drafts you should be good with pretty much however you lay it out. I did consider this myself and am placing my nest boxes on the opposite side of where the wind primarily blows, same with the roosts. The nest boxes will be where there is the least amount of light and my roosts will be by the window and pop door so they can look outside. Hope that helps.

 

Yeap, it doesn't really matter much overall. It is best to have the popdoor on the side that will be usually-downwind in wintertime. If you live in a cold winter area, it is best to have the roosts as far away as possible from the vents you'll be using in wintertime, which will be on the usually-downwind wall so therefore a lot of people would site the roosts near the upwind-in-winter wall (unless you're in a warm-winter climate). Although, in a big enough coop you can get away with almost anything

Feeder/waterer and nestboxes don't usually depend much on compass directions, it's just whatever makes sense given the rest of the coop layout.

Good luck, have fun,
