I have big parrots, and dont use applewood as perches, since the only natural wood we have that they cant chew apart in a matter of minutes is ironwood..I use that for perches. I do put applewood branches in for them to "keep them content" by shredding the bark off. and making toothpicks out of the branch. :bgrin I have been doing this for years, and have never had any problems. We have our own trees, so I know they are not sprayed. Corinne
