96"(8ft) by 80"(roughly 6.5ft) and 80" tall. Plastic pallet floor. I have an exterior door I am installing on the open walled side, than I will put in the rest of that wall, and ceiling. Install 3 nesting boxes and sleeping quarters, than fence in the approx 50ft by 50ft run area. I have a smaller coop now just big enough for my 3, but I have 16 chicks in the house that I am keeping I think 7 of, maybe 8. Not sure, need to wait to see if 2 of the ones I want to keep are pullets. So this coop with 52 square feet of floor space will house 10 chickens or so, and 2 of them are Jersey Giants(1 pullet, 1 roo I believe). So plenty of room I think. I plan to have 2 roosters and 8 hens total. Oh yeah. . . . and 1 handsome weimeraner lol
