Hi ya'll - new here and my first chicks arrive on Friday. I'm all set with the brooder, though I think they will outgrow it pretty quickly. My question is this - I live in Central FL and the building that I am converting to a henhouse has an area that has a solid wall to the north, this is also an interior wall that has stalls on the other side. The other two outside walls, facing east and south are slatted. The fourth wall I will have to build, it opens into an interior area also that is a10' wide area that is slatted also. Being in Central FL, how enclosed does the coop area need to be? I was planning on lining the interior with chicken wire and also bending the wire to the inside (dirt floor) then covering the floor with heavy rubber mats. Do I need to make the walls solid? Also - I ordered 25 chicks, the inside area is 9'6" x 11 and they will have access to at least a 20' x 12" exterior covered pen. Is that sufficient space? TIA for the advice!
