chicken suddenly wobbly

[bigmommasilkie]

Hi, I have a one year old Brahma..she was completely fine last night. Tonight I went to the coop and she was laying on the floor of her coop, not on her perch, very unusual for her...she saw me and got up..she was very wobbly, she would stumble and wobble. I brought her in the house and checked her over, no injuries that i can see. Her legs seem fine. No parasites that I can see. She lives in my backyard with three other chickens, all others seem to be just fine. I am at a loss as of what to do or what could be wrong. She is eating and drinking fine. Any help would be greatly appreciated. Thank you
