I did a search for 'coop foundation' on here and my head is spinning. If we have a 5 X 8 (or 6 X 8) coop that's about 4' high and about 18" off the ground...what kind of foundation are we looking at? We live in Connecticut - so we expect the winters to be pretty snowy - and long. The ground we're building it on is - um - average - not particularly rocky or sandy - nothing stands out. Doesn't 'flood' necessarily and drains off okay. Given the size of the coop (and therefore the weight) will it be enough set it on the ground? Or on top of cinderblocks? Anything? Do I have to worry about it blowing over? Thanks!!!
