Hello, We have lost three hens in the last two months the last one just today, all less then a year old. They seem very alert, eating drinking just can't walk or stand. When we brought them in the house and nursed them in about two weeks they seemed to be better getting up waking. But when we put them back into the hen house the next day they were dead. There were no wounds of any kind that we could find on any of them. Does anyone have any idea what could be causing this strange condition?
