A question has been eating at me for some time now...I just recently built a chicken run with wood (duh ) and hardware cloth. At the time I was hurrying to get the run done. It hasn't rained yet but I am concerned that I should have sealed the wood (is this the right terminology? I am total foreign to many things in the hardware store...) beforehand. Is it too late to seal the wood? Can I just brush on the sealant onto the wood and some of the parts that have hardware cloth covering the wood? I'm hoping that if I can do it (and it's not toxic to chickens) then the run will last longer. Any suggestions on what kind of product to use to keep the wood from absorbing water and becoming weathered?
