Good morning, I discovered yesterday that one of my six-month-old Rhode Island Red pullets has a larger-than-a-tennis-ball swelling on her rear-end. It's soft and kind of squishy, but she's eating normally and gets around just fine. I did isolate her to see if/what she was pooping, but nothing in the 90 minutes I had her under (my) observation. Online I found the following videos that seemed to address both the symptom and how to drain: How to drain: How to drain a bird with ascites: I'm wondering what I might be missing before I attempt any 'needlework'? Thanks, everyone!
