Tumor in chicken?

[Blue Raptor]

Hello BYC! My SLW has a swollen abdomen, a poor appetite and is thin, and has impacted crop. She has no outward appearances of a sick chicken other than slowness. I though she may have a tumor, and I’m treating her crop now- suggestions for what this is and how to treat?

Thank you. Here she is, her name is Bess.

Alright, here is an update:
Bess doesn't have impacted anymore and I have been giving her some egg and keifer and electrolytes to keep here energy up. She's still thin and isn't eating much on her own (how can I encourage that?). She had bumblefoot on the farthest left toe on her left foot (you may be able to spot in pic above.) so I dealt with that yesterday night. I compared her abdomen to other flock members' and it's actually fine.
