What is wrong with my chook

[momachick2]

Hello
Could anyone give me advice. My chook has become distant she has lost weight she has runny poo.
I only have the 2 hens
With this I took them both vets she was seen to and vet said he could feel a slight inflamed intestine or it could be a tumour.
He gave me antibiotics for her and said if she dont get better what would I like to do.
She is eating fine drinking running around. No nasal drip her comb is fine eyes fine everything apart from weight loss and lose stools and distant.
I feed her well pellets,meal worms,melon,oats, fresh water.
Im worried about her she dont lay she is 2yrs old. The other hen is fine but these girls are my pets I adore them.
Is there any advice on what to do I am at a loss.
Thank you for your time I dont come on here often so plz bare with me working my way around on here.
I just dont want to lose her xx

It would need wormer if it's worms...Did the vet do a fecal test?....Could be coccidiosis?...All birds have it, just some get an over load...
