liquid squishy lower abdomen

I've never had a hen do this but I have a hen who behind the legs the lower abdomen headed towards the tail is swollen full and it's squishy like it's filled with water.
Any ideas or suggestions?

I've been doing some reading and my guess is she probably has this condition that everybody is calling water belly. I don't see any signs of pain or labor breathing but she's lethargic and separating herself. so is there any chance of this actually getting better. I read several people talking about draining it, but no actual solution with that so is it just better to cull her now?
