I am building a coop that is 10 x 12 and was going to put a shed roof on it. The coop is placed on cement deck blocks and is raised a half a foot or so. The walls are 6 foot on one side and seven feet on the other side, the ten foot length in between. I read last night that if it isnt tied down, It can blow over in the wind! That source said the walls can only be 6.25 on the high side if the depth is 10 feet. Now i feel like I have blown it and I am halfway finished. Is this true? I don't know what to do now.
