You're speaking with Dr. Michael Salkin. Welcome to JustAnswer. I'm currently typing up my reply.

Please take a look here: and tell me if that mass represents a prolapsed vent. If so, there are instructions on how you might address it or an avian vet (please see here: can attend to Speckle for you.

I have looked on the websites...that's why I paid for some help...she has had the treatments recommended on them ...bathing ....looking in vent for not feel one...her bum is ver red and swollen Pretty hard....but nothing is hanging out of the vent ....this is day 3 she seems pretty alert...but ..what do I do about this issue
Expert:  Dr. Michael Salkin replied 1 year ago.

Ah! I see what you're saying now. It's possible to have a prolapse that isn't visable but that's not going to cause a swollen mass large enough to cause her bum to "hang". You appear to be describing ascites - a collection of fluid in the coelom (abdomen). That's seen with right-sided heart failure, liver and kidney insufficiencies, a yolk peritonitis (unlikely if she's "pretty alert") or neoplasia (cancer) in the coelom. How old is Speckle, please?

Customer: replied 1 year ago.
She is around 3 years old
Expert:  Dr. Michael Salkin replied 1 year ago.

Thank you. Would you consider her overweight?

Customer: replied 1 year ago.
No she is not fat
Expert:  Dr. Michael Salkin replied 1 year ago.

Thank you. She doesn't fit the picture of a heart patient with an effusive (fluid-filled) abdomen. An inflammatory disorder in the coelom (infection, neoplasia), salpingitis (infection of the oviduct) with retained eggs, liver or kidney insufficiency resulting in hypoalbuminemia (decreased serum albumin level) are all considerations. Unfortunately, none of these disorders can be identified and then treated without the help of an avian vet. I understand that it's best to approach the diagnostic process with a clear sense of Speckles's value to your operation. Although some services such as your county animal disease diagnostic laboratory might be available free of charge through a county agency or land-grant extension office, the expense of some diagnostic tests and treatments can add up quickly. While it’s always worth your time and money to identify a bacterial or viral infection that could potentially impact more than one member of the flock, this might not be the case with a condition that only affects one hen. It frustrates me that I can't be more specific for you but such is the dilemma of poultry owners and vets alike.
