ok i forgot to say that my grass isnt flat and slightly slanted. does anyone reccomend anything as far as placing a run or coop on the grass? i have a rabbit and a tortoise who atm are part time sharing a large run. we find it hard to place it without it being gaps underneath not huge but still. luckily the bottom is covered in a plastic netting. however the chickens will be out there permanently so i want a way to solve this problem for good.
