Thanks so much for all your help.
I will pluck up the courage to have a better look at her tomorrow. I haven't liked to man-handle her too much in case I am causing her alot of pain. I will check for bumblefoot but other than that there isn't much i can do to help her more than I have already done.
I put the low heat lamp on her at night as I figured a group of hens in a house create abit of heat, but her on her own in a cage might get cold....Yes, I know I am soft
She seemed to perk up in herself today and was clucking away and eating and drinking, she is still not wanting to put any weight on her bad leg.
Unfortuantely her cage will not fit in any of the hen houses, so not an option.
I will keep an eye on her, I have dosed up her food with poultry spice and a drop of Apple cider vinegar in her water. She won't eat mashed up egg, but does eat her mixed corn bedtime treat.
Bloomin hens, its one thing after another lately.
Thanks for your help again all, I will let you know how she gets on.
