Has been sleepy for a couple days, did eat 2 days ago, now eyes closed and laying on side, she looks to be in pain. Flails around a bit flapping her wings. Laying on her side. Feels thin. Pasty butt, thin, no sour croup smell, no visible wounds, feels like a lot of fluid in lower abdominal area under tail. Checked for egg bound -- no egg. PLEASE HELP. 2 years old hen has always been healthy. ** Edit for typos and additional information.
