Well, we just started working on our coop. I drew up the plans myself, inspired by the Purina Henhouse (http://poultry.purinamills.com/NUTRITIONMANAGEMENT/HenHouseHutchDesign/default.aspx) but modified to fit the size of our flock and to take advantage of the space they will be kept in. We have a shelter attached to a garage (it has 2 walls, we'll be using one of the walls as the back of the coop). I decided to put nesting boxes on both short sides (3 boxes per side) of the 4X8 cause we'll be having around a dozen birds. However, I then saw an open air woods coop and after doing some work in there today, I'm worried about ventilation (cause there was no air moving under the shelter and it was hot). So I may make that side just a giant picture window and possibly double up the nesting space on the other side. The birds will have a large fenced in run, but I'm worried about enough ventilation at night, though, nights are pretty cool even in the heat of the summer here in NC. Anyway, I'm doing the floor right now (will be lining it with linoleum using furring strips to secure it to the floor), if you have any suggestions for the rest of the building, let me know.
