I am in the process of demolishing an old chicken coop. All of the
wood has by now fully greyed, and none of it appears to have greenish
tinge to it. Some of it was clearly hardwood (judging by the smell
when cut, and by a red color inside, probably red oak) but some was
pine. There were no apparent green colors inside the wood, but I still
would like to be sure. BTW I am aware of the "send a swab to the lab
for Arsenic testing" option. I am hoping there are easier ways of
telling.
