The 10 x 10 shed conversion is almost complete. I painted the interior, installed 4 windows and the linoleum floor this weekend. The first 6 hens will be in by the end of the week. My questions are these. There is a big willow tree that hangs over the area that will be the run. Is this a problem? Also I want to get the coop up on blocks. It is just sitting on 2 4x6's now. How high should I put it?
