Where did this bird come from?
Mareks can only be positively diagnosed by a lab doing a necrospy,
might want to start researching one nearby just in case she doesn't make it.
It can be expensive or free, contact your extension office for some leads.
It's usually fatal and all your other birds...
Yes, can see the vid now, thanks.
When you pick her up is she moving her legs at all?
They look paralyzed.
How old is she..I'm guessing about 8-10 weeks?
Is she eating and drinking and pooping 'normally'?
Video needs to be up loaded to youtube and made public.
Can't really tell much from the pics.
'Sitting' pic from front and other side might help.
Maybe hold her on her back to see the alignment of her legs.
Hard to say what is wrong or what to do....if hip joint is actually dislocated probably...
