I was holding my little chick a few minutes ago, and I noticed that it kept picking at the base of its tail on its back. I took a look and it has what looks like a little skin tag. Do chickens get skin tags? What else could it be? Obviously it bothers the chick, unless it just picks at it b/c it is different. Should I just leave it, or do something about it? I would take pictures, but I can barely get it to hold still long enough to look at it. I'm not coordinated enough to hold it and take a picture of the teeny tiny thing on its back.
