2 1/2 month old Cuckoo Marans trouble standing

[RottyChicDog]

My young Cuckoo Marans is having trouble standing, seems thin in the breast but otherwise healthy-looking. Only eats 20% chick starter and hasn't been outdoors yet. Other 8 show no signs of illness. My poultry vet moved away..ugh!
When she stands she stretches up like a cat. She's eating and drinking, I took a fecal to the vet today to be sent out. No sign of mites. She will sit back on her hocks and stand one foot on the other like she isn't balanced. She also has a slight twitch at times and will hold her tail to the right. She does stand and walks a bit to eat and drink.
I've been giving her Poultry Nutri-drench twice a day, .50ml.
She's alert but I've never had this happen before and have been raising chickens for years.
Any ideas? Could this be neurologic? Video link at the top

Thank you.

Looks like Mareks to me. If it is generally they will continue to worsen.

They were vaccinated for it.
I did just get a call from the vet, she tested positive for coccidia, so I will treat the whole flock tomorrow with Corid.
Thank you for the reply, I will research more on Mareks.

The crooked tail is interesting, and may just be a defect called wry tail. I think Mareks could be a possibility. But there are some spinal spondylopathies that can cause a crooked spine which can cause leg issues and lameness. Since she starts squatting on her hocks some, I would definitely start some B complex vitamins 1/4 tablet daily, or give some chick vitamins or liquid baby vitamins with riboflavin. That would help if she has a riboflavin (vitamin B 2) deficiency. Poultry NutriDrench does not have that, but you could use Poultry Cell. Any source of riboflavin is good.

Thank you for replying, I will read the articles and start her on the vitamins.

I had the Department of Agricultural come out and do testing on this pullet and my adult flock. They came back negative for Mycoplasma, Avian influenza and New Castle Disease. Those are the only ones they test for here in WV. After the results were back, I euthanized the pullet in the video as she was declining and we concluded she had Mareks. The rest from her hatch have shown no signs of disease, she was vaccinated against Mareks but it is still possible for them to get it, they just may not have text book symptoms.
