Thinking of making my roost with 2x4's. That will give my girls a flat for their feet. Is there anything wrong with doing so? It will be 3 or 4 levels high. About 4' tall for the highest level and lowest being around a foot off the floor.
I just built a 7x8 coop with a wood floor and linoleum on top. Run will be 8x12 about 6 1/2 foot tall. Concrete is expensive and wouod be an easy clean up.
