I have a 3 year old silkie hen that I found lethargic this morning. She feels very thin and bony but her abdomen feels swollen. Also this morning her crop is still full. Would having a sour or impacted crop cause her abdomen to be swollen or is it possible that the swollen abdomen is causing her crop not to empty? I brought her in and put her in the hospital cage, she has had one watery poo. I haven't tried to feed her since her crop feels full. She has water with ACV in it. Any suggestions on what I should do?
