I have a 6 month old Barred Plymouth Rock hen. She has been laying for about a month now. Today I went to feed them and she wasn't too interested in the food and I noticed that she had a dirty vent. It was not clogged, so I wiped it best that I could. She still looks a healthy weight and I am pretty sure she is still laying. Her vent was a normal color. I noticed while she was near the feeder she vomited about a quarter size amount of what looked like water.. I don't know what to do but I need help fast in order to get her medicine, I live in a rural place and will have to drive about an hour or order it online. Thanks to anyone who has any ideas!
