I think it may be a peritonitis (sp?) as she has a huge swollen abdomen which is very pink, and waddles around like John Wayne

She has been like this for at least three weeks - and has been eating and drinking and running around without any problems and has a very deep red comb.
I have done some research - I gather there are two types of peritonitis - septic and non septic. Given that she is eating and seemingly happy (although has laboured breathing) I don't think it is septic - and gather that not even very strong antibiotics can treat this anyway, so don't want to stress her with a trip to the vet if it won't help.
So I just wondered what you would do? I have read about how to drain it with a catheter


Just wondered if anybody had any experience or thoughts on this. Incidentally, we lost another hen to what I now realise was probably a septic peritonitis last week. I didn't think it was an infectious condition, but if anybody knows otherwise, I would be grateful to hear. Have isolated sick bantams drinking water just in case.
Thanks all in advance...
