Sick Arucana

[Crahmsy]

I hope someone can help. I have a sick little blue Arucana. She is a rescue chicken and at least 8-9 months old. She has never laid an egg. She is part of a flock of three that we homed at the same time - the others are an Isa and a leghorn cross, so much bigger than her.
In the last few weeks she has lost weight (now just over 500gms), her wings have dropped, she has runny poos, her foraging has reduced, she has become unsteady on her feet and often trips and falls, cannot climb over objects that she used to, she looks a little depressed and spends a lot of her day with her head bowed down and eyes closed. She also seems to be trying to snuggle into and underneath the other two which they are unhappy about.
I have taken her to the vet - he didn't know what was wrong with her, but put her on a course of antibiotics to see if that helped. It didn't - he is a lovely vet but I don't think he knows much about chickens. I have also been feeding her mealy grubs by hand to supplement other food, which she loves. It has just gotten cool here in Sydney (sub 10 degrees C overnight), I have tried bringer her inside where it's warmer, but she has pined for her friends so is back in the henhouse. Since I've had her she has been regularly wormed.
She is such a lovely little thing and my kids absolutely love her. Any advice would be appreciated BYC folks x

She could possibly have something like Mareks disease, but I would give her poultry vitamins and probiotics in her water, just in case. When you go out to visit her bring her some scrambled egg, and buttermilk contains probiotics if you can't find them. If vitamins for chickens can' be found, dissolve some human B complex tabs in the water daily or offer some nutritional yeast in the feed.

I would try treating her for coccidia. A lot of the symptoms you describe sound like coccidiosis.
