I had help to put this together (roost is on the right, nest is on the left). Does anyone know if I should paint the new roost with linseed oil or something to keep mites off of it? The wood was all salvaged. Also, the roost comes out easily (the 2 bales of hay keep it in place) but is there something I can do to make cleaning it out easier? I put lots of hay down, but what do the rest of you do?
