Just doing a once over on our two new babies. The silkie hasn't seemed to thrive as well as our other EE chick. As I was checking her neck I found a berry sized fatty lump. I'm worried about Mereks. She came home as a day old chick two weeks ago. We have a small flock of 4 layers. They have separate areas from the grown girls. Any help would be appreciated. This is my young daughters chick.
