Mareks?

[Sberrie]

My ~6 month old Salmon Faverolle pullet started to show signs of lameness last week. We isolated her, started treating for vitamin deficiency. But she seems to be getting worse. I suspect Mareks although she was vaccinated.

First two pics are current. The other is from a couple days ago when she could stand.

Sadly, I do think it is Marek’s. We lost a Faverolle at that exact age to Marek’s with the exact same symptoms. She had no response to supplements etc and passed shortly after. I’m sorry, I hope it’s not the case!
