Morning, thanks for your replies, every little helps! Well Nigella is still with us, been a hands on, full on experience so far!
Just been out again and fed them scrambled egg, bread, meal worms and chopped up greens with added diluted ACV and garlic, was suprised to find Nigella had made it to the outside perch we had built for them, she also made it in the hen house by herself last night, the night before I had to take her in and her eyeleids were closing, I really thought she was going to peg it by the morning. ANyway she is still puffed up but drinking water (the citricidal is totally natural, no chemicals, Citricidal is a natural anti-viral, anti-bacterial, anti-parasitic and anti-fungal derived from grapefruit seeds has a whole range of applications for ultimate microbial protection.) and stops the water turning green and does them the world of good! Even so we change the water every 3 days, at the moment changing every 2 days and cleaning everything each time. Poo is still coming out yellow and white but no blood anymore at all. Looking almost perky this morning, cleaning and preening, and EATING! Just saw her eat two lumps of scrambled egg and shell topped with live meal worms, also have been watching her drink quite a lot of water.
Back to the vet tomorrow and Tim I will ask him about what you have said.
On the conversation with dairy products, how do chickens get their protein to lay their eggs? I was reading on here a lot of people give them yoghurt, up to now they have only had chicken pellets, bread, and have the greenery out of my garden. Will not give them yoghurt etc til I've heard back from someone, I read on a chicken advice sheet that they eat everything?
Will keep you posted! The bad news is my 5 fish in the aquarium died! Gutted, the heater went wrong and my dog ended up in the vet yesterday with a bacterial infection caused by the dog groomer! The vets telephone number is like a hotline number in this house!

Thanks for everyone's advice!
My best friend runs a pet supplies shop, he doesn't sell this but one of his customers who keeps lots of chickens swears by it!
