Hi all, I have 1 of my 8, 4 week old chickens with a fluid build up on its breast region. It is fluid like to touch and in my opinion, quite large for such a young bird. I have heard the term sour crop and its symptoms sound the same. My chickens are on a chicken starter mix for food and have the water changed X2 times each day. How can I treat the chicken with suspected sour crop?
