So we built our coop last winter its 8x8 with a run thats 18x18 now ive done the math and an 8x8 coop holds 16 chickens but last year we had like 27 in there no problem with plenty of roosting space but then some friends built a coop so we just gave them half so they didnt have to spend the money on new chickens that i got mostly given to me how many chickens do u think i could have in my coop and run?
