I am planning on having crested breeds. Do those with Poland, Brabanters, Houdans, etc have covered runs (I plan to have chicken wire over top for hawk protection, but am wondering beyond that. I would love for the birds to get sun when they can, esp. in winter. We don't get a lot of snow and summers are very hot and dry (but humid.) I am afraid the cost of covering the runs would be prohibitive (on top of my plans for the coop.) Any of you with Polands or Houdan or Brabanters or Sultans have any advise on your experience? Thanks.
