this morning I noticed my hen hailee acting strange. She is molting and will be two in March. This morning she was just standing around with her eyes closed- which I know is normal for molting hens, when I tried to catch her, she ran normally and as she slowed down she kind of dropped her wing and was walking off to one side, kind of losing her balance. There is a video below. Is this mareks? Or a vitamin deficiency? My sister said she jumped out of the nesting box and stumbled, but I felt her legs and can’t find any obvious breaks. Please help! Also she is eating.
