HUGE balloon under her belly!

[Chickie-chan]

My barred rock has a huge balloon under her belly! At first I thought she was egg bound but when I gently felt around it didn't seem hard, but squishy inside. So I did some research and found that she most likely has ascites. I promptly went to drain her and found what I was sucking out was dark brown liquid, with some underlying blood. I used an 18 g. needle 1inch long so I was pretty sure I hadn't poked any of her organs. The balloon was HUGE so I thought I was in a safe range too.
All the other pictures I've seen it was a straw/yellow colored liquid not dark and brown. Has anyone else had a darker color too? Did I accidentally suck out something that was needed?

I'm wondering if she has an abscess of some sort. I'm no chicken expert, so I would wait until someone else answers. I am a critical care nurse though, and the drainage sounds like an abscess. I know this is gross, but what did it smell like?

I'd be interested to see how it turns out - one of my red sex links has been feeling a little heavy whenever I pick her up. She is still laying, eating, scratching and acting normal, except that she is reluctant to jump very much. I think I can feel a waterbaloon but as she's so healthly, I'm reluctant to intervene and risk making it any worse...
