I just did it for the first time 2 days ago. Favorite hen, 4 yrs old… her belly felt more like air than squishy but something was wrong. I didn’t think it was egg… so I read a million posts, videos…
My husband held her, I had 16 gauge, 1/2 inch needle, 60cc syringe, rubbing alcohol and a spray wound treatment. Stayed on right side, 2 inches down from vent and to the right towards leg, insert at a diagonal. Urine looking liquid, took out a cup and a half. Hardest part was unhooking syringe from needle to empty and then replace. I did have to poke a 2nd time. She was not all that upset, wrapped in a towel. Sprayed area again after removing needle. Let her back with flock after an hour observing. Kept looking for signs of infection or refilling. So far none of those, I can tell she is more comfortable. There is still about as much left in her. I’m going to drain the rest tomorrow. She had been this way about a month and has lost weight. I feel she will have the best chance get all the fluid off and see how it goes.
I’ll update if she’s still here in a couple weeks.
She was not so full she was weeping from her tummy but now that I drained a lot, I imagine it really doesn’t feel good. I’m glad I did it. If it becomes a monthly thing… ugh likely not good quality of life for my girl.?
