you all in the south are lucky that is all you need..up here we have to have more protection. My coops are all walkin types, 2x4 framed, with full insulation and OSB on the inside..the next coop we build will be of SIPS panels, which is a OSB with a styrofoam inner layer 1/2" thick and then an OSB layer like an OREO cookie..extra strength, and great insulation.
It gets COLD here.
I do envy your nicer weather..
