Hen with tail down

[Animalmad12]

Hi, we brought 5 pol hybrid . When we got them home one of the girls has her tail tucked under, we told the breeder but he wasn't interested. They were in transit for over 24 hours, so we hoped it was stress and she would recover. 2 weeks on she is still has her tail tucked under her, she is eating and doesn't seem to be in any discomfort. I'm not sure what else I can do to help her, any ideas?

I would take her to a local avian vet and get a blood test done-----not cheap(approx £150 seems to be the going rate & they are also likely to put her on a course of antibiotics), the blood test will show up a lot of any internal problems that you would usually never know about.
You could try worming her, but this may well make her worse.
They are very good at hiding problems until it they are too advanced to do much about.
The breeder should advise/exchange the bird if there are problems:-So if they are not interested in the birds welfare??????????????????????????????????

Have you got any photos? Has she got ruffled feathers? What does her poo look like? Can you see any blood in it?
