Month old silkie chick has large soft mass on abdomen ( had since birth)

[NewDuckMama4]

Well I only attempted to do it on the right side which I understand is safe and free of Organs
..correct???
But my needle was too small so the syringe was super hard to pull so I stopped and I'm getting a bigger needle tomorrow so I isolated her and gave her some chick boost with probiotics and dried oregano...
I thought about just leaving it because it's not really causing her any problems but the more I've read the more I worry about her all of a sudden going downhill or worse and me wishing I would have drained it sooner I'm thankful for any opinions I can get

As far as I know the entire abdomen holds organs, but I think if your careful you should be fine. I'm no expert though and I haven't dealt with anything like that so I'm not sure. Hopefully someone more experienced can help you!
