My young Barred Rock (not laying yet) has swollen eyes and looks like her crop is swollen. Have separated her from flock, she drinks and looks like she is eating a few pellets. Her poo or vomit is watery and green. I gave her bread with olive oil and massaged her crop. When doing so she looked like she was trying to vomit, but nothing came out, yet it smells bad. I am hoping this wonderful community will have some advice for me. oh, she has been like this for 3 days. Thank you for your help.
