Found this growth on the periorbital flesh of one of our chickens. We had just purchased four new girls and they had only been with us about 48/72 hours. Any idea what it could be. We'd decided to watch it for a couple of days to see if the raised area was a hematoma or an insect sting, thinking that it might go away with time. It has been about a week with no changes either way. Would appreciate any help you may be able to offer. Pictures are attached.
