I just put my young 7-week old pullets outside yesterday with their hutch made out of stained pine. While they were foraging around the fenced-in garden area where they are going to live, I noticed today that there was a large bee on their perch in the hutch for quite a while. I removed it with a paper towel, but it came back later. I thought at first it was a bumble bee, but noticed that it had a smooth all black abdomen. I looked it up online and found out it is a carpenter bee, which bores holes in wood to lay the eggs. I noticed that in fact it did bore a hole in the perch bar. I covered the hole over with some heavy tape, so it was not able to get back to the hole. Is there something I can treat the perch bar with, so that the bee(s) don't come back to bore another hole, as two bees came and inspected the tape-covered hole? Of course, it will have to be safe for the young chicks since they will be perching on the bar. Thank you for any help you can offer, as I am very distraught as a newbie chick mom, since I don't want my chicks to be hurt by the bees in any way. I know only the female carpenter bees have stingers, but I don't want them to sting my chicks. I am very concerned, and looking for a safe solution. Thanks you very much, Joan S.
