I think I'm going to lose my girls :'(

Thanks guys  I spoke to a vets in Stowmarket and they were very helpful indeed but I'll keep Highcliff's in mind if needed as its nearer.

The vet said to keep an eye on her and give her a bit more olive oil & yogurt as she could have a little infection in her crop after being ill the other day, it seems to have sorted it right out and she's back to normal thankfully after all my worrying!! And these are chickens, imagine what a bag of nerves I'd be if I had kids!!
