Chicken not acting normal.

[hoosiersphynx]

My one girl Shelly got out of the coop about 2 weeks ago and has not been acting right since. I am think that she could have hit her head when she got out of the coop. Some chicken wire came loose and I think she fell. When I go out to feed them I open the door and let them come out while I am feeding and watering them. When I am done I use my foot to kind of push him back in the coop. When I do this to Shelly she will take a nose dive. If I pick her up she will tuck her head down like she is plucking at her feathers on her neck. She is still eating and drinking fine. Do you think that she has some brain damage? Do you think that she will still have a good life?
Thanks for your help
Rebecca

Any other birds acting odd like this? Do you know if she has been vaccinated against Marek's?

Sounds neurological your right, look for mold anywhere around your coop
