Hi All. I was able to get a large amount of apple wood from a local orchard. I want to make a bird tree out of some of it. I do have thick pieces that branch out and can add to it. My question is this: If it's too large to put in a tub or oven how can I safely use it to make a tree without introducing parasites or mold to my birds? This wood is freshly cut with no visible mold.
