I have a chick that hatched on Monday, and arrived Wednesday. Yesterday I noticed that she had a very large swollen "lump" on her right side. After doing some reading the only thing I can find would be sour crop. All she has eaten is chick starter. There has been no smell thus far. I tried to take a pic but she would not stop squirming! Can anyone help? What can I do for her? One of the others arrived with a prolapsed vent. Not a good week for baby chicks! Thanks!
