For awhile now my hen has had this big bulge at her butt. Butt recently it’s gotten bigger. I did some digging and found out that it could be ascites. I bought some needles and got ready to drain it. It felt like a water balloon so I thought it was a good sign. But nothing but air came out. I couldn’t get any fluid at all. I tried a few other spots thinking maybe I missed it but the same thing every time. The bump went down a little bit but it’s tell felt like there was a water balloon. But when I was feeling I felt something. About the size of a golf ball. But it was fleshy and hard at the same time. Now I’m scared it’s a tumor or cancer. Any idea what it is?
