One of my 7 week old babies (silver penciled cochin) has a strange bump on the back of her neck. It started out a little over a week ago as just a tiny real red spot and now has grown to about the size of a nickel and is raised and fairly hard. She is eating and active. No other problems as of yet. Has anyone seen anything like this? And suggestions as to what to do? Thanks in advance Jacie Click on image to get larger image.
