Hi, we purchased a baby chick yesterday. At first we thought she was a runt, but Upon further look, she has a big bump on her neck. Looks kind of like a blister. She can't bend her head really, so you have to water/feed her. She doesn't walk well either. But she is a sweet heart.It's almost clear and you can see veins thru it. Has anyone seen anything like this? I'm not really sure what to do for her.
