My chicks' coop gets sun from the south on the back side of it, and my chicks like to bask on sunny days. But they don't have any protection from the wind, so I am thinking of attaching a sheet of Plexiglas to block the wind and still let the sun through. I am concerned though, that the sun beaming through the plastic will actually be too hot. Is it a good idea to use clear plastic as a wind block? I happen to have a piece the right size. Or I could go get some thick plastic sheeting that is opaque. That would be sort of a compromise between basking in the sun and being in shade.
