Just curious, how many of you are using footings of some sort under your coop? I am not concerned with the small "rabbit hutch" sized ones, but more on the line of small shed sized ones. I am now at a coop about 8x8 in my planning stages and the framing will most likly just be 2x3's to keep the weight down. I do have to deal with frost so I am wondering if I should just pour 4 sonic-tubes and build off that, or how many of you have them "floating" on blocks. If you "float" do you have any real issues with the coop sitting crooked over time or has it been ok? I am just worried that I will have door fitment issues and window problems.
