I'm building a pallet coop, 4'W x 11'Lx 6 1/2'H and not sure which would be the best way for the roosts to be built. Please see photo. Long way - easier to clean poop tray, all chooks are on the same roost height, etc., but I get 3-4' less roost space...total of about 11-12' of roost. Short way - planned on making the roosts bars easily removable to get to poop tray, have a long kitty litter type scooper and get a little over 15' of roost. Can make them all the same height, or with where windows are, easily varied 2 1/2-3 1/2' off the floor and still ventilated, but no drafts on the birds. Will have 3 windows total, 4" venting covered in HWC at roof level on both long sides. The coop is shielded by a garage on the south side, half of the north side by a shed, east has large lilac bush/tree about 4' away, open to the west but no north wind whipping by due to another garage there. Brooder coop will go under the roosts, whichever way it goes...2' wide x 6' long...with removable panels if I want open space for the floor. The chooks are only in the coop at night. They free range a large yard right now and will have an 8'x28' run soon. In Northern Colorado, mixed flock of a dozen or so - GLW, LO, BO, BJG, BR, DEL, Welsummers, a couple of bantams. I hope that answers any random questions that may come up in contemplating the roost placements.
