It was mighty icy last night and I thought I had all of the chickens inside. My DH opened the hatch this morning. I went out around noon, to visit and check on water, and one Wyandotte pullet was outside, on her side, eyes shut, mouth agape with snow in it. I'm just not convinced she's completely dead. Of course, can't reach the DH to find out if he saw her outside this morning. She's inside now, by the woodstove - how long do I give her to decide if she's really dead? Is there anything I can do to bring her out of shock, if this is what's going on?
