The chickens love their new shed…it was not the easiest to put together, but the struggle was worth it in the end.  We took the window frame and put 14 inch wire mesh in for air circulation (gets hot and humid in summer).  We have not done the final roosting bars and only put in one set of nesting boxes.  I suggest only getting the sets of two and put them stacked on the short side of shed.  But we are overall pleased with the shed.
