We cut our own tree locally, it's a great source of income for smallholders around here. Most don't treat the trees with anything, at least not out in the field. We don't use any tinsel on the tree and we feed it to our goats, the wethers or the kids. It's "goat chocolate," one of their favorite snacks. We don't give it to the pregnant does because some say too much evergreen can cause them to abort. I don't give it to the milkers either, because it makes the milk taste funny. So our poor chooks don't get to play with the tree at all.
