Only place I can think where one would dissect a human cadaver.
Here's some basic guidelines on coop design:
Minimum of 4sqft of floor space per bird in coop, 10sqft in run.
12" of roost length per bird.
1 nest per every 3-4 birds.
If you can't build yourself, a prefab shed is a good way to go.
In your climate you want more mesh walls than solid walls.
