I'm planning my next coop. I'm going to build a simple shed type shelter. I want to house 6 chickens, winters are pretty harsh so I was going to give each bird 10sqft, I imagine the birds will spend some time in thier on snowy days. I've seen some other coops that were attached to concrete blocks that are laid directly on the ground. These blocks sort of look like triangles with the tops taken off. I was wondering how you attach the floor of the coop the blocks. Also are they heavy enough to keep the shelter from tipping in windy weather. I planned on making the shed 8x8 so I'm not sure how many blocks I'd need. Any advice or tips would be much appreciated.
