Sick hen, poop seems to be backed up

[Chicken Whisperers]

Yesterday we noticed a 6yr hen of ours was walking funny, and today she is completely immobile and seems to have a large lump near her abdomen. We’re thinking it could be poop or an egg, but nothing for sure. Comb is also bluish in color (shape is normal, it’s been like that for years). Any advice or help is welcome, we’re worried she won’t make it through the night.

Looks like ascites/water belly stance. Look up ascites to see if it’s a match.
