Karma in farm life

Today Elsa was found dead in my yard, no apparent cause. She was alive and fine at 5:30 and stiff at 8. Izzie is also missing. Since she's the one that's impossible to catch unless she sleeping I have no idea what could've gotten a hold of them, besides karma catching up to me for killing the rooster.

So I found izzie this morning. I searched the yard from 6 to 6:30 and didn't see her and then went inside and saw her trying to get into the coop at 6:45 right before I left for work. I feel bad she spent last night in the storm and I didn't really think I liked her this much. I kept them all locked up today and didn't look her over because I had to go. Still sucks Elsa died. She was my best layer
