So I got a used coop for Christmas. It's 4x4 and seems to be pretty well made; it's off the ground and quite sturdy, with two nest boxes, a roost, a window for light, two large ventilation holes (slits really, directly across from each other so there's a cross draft) that can be opened and closed at will, and an inclosed run with a wire roof (I'll try to get some pictures up soon). Really my only problem is that, since the walls are so short, the ventilation is very low (if it was higher drafts would blow directly on the roost, which would be bad.) How will the low ventilation affect the chickens when its very hot or cold? Is this good or bad for the build up of ammonia and such? What about moisture? It gets very cold here in the winter (I live in northern Ohio) and I'm worried about frostbite. Also, I'm wondering about the deep-litter method... can it work in a small (4x4) coop? How high does the litter get? If I can't leave it for more than a few months, or less than that even, will it still work the same, or should I just plan on regularly changing the bedding? The little panel you can see on the side is one of the ventilation slits. The inside ^ The left side: the wire is where the ventilation slit is. The box you can see to the left is one of the nest boxes. Right side.
