I went out there tonight and put the chickens away, but when i got outside i had a golden laced wyandotte ( of one year old ) laggin behind. sorta frustrated since it was cold, i hurried and tried to hustle her in, i looked at her and realized one of her legs didnt work. I picked her up (which was easy to do), and inspected. It was spongy, and had absolutely no strength at all, like it was deteriorating, still color, but its vanishing. I have no clue what this is? I have her isolated, help!!
