Back when I used to raise chickens, my hens liked to create stealth nests. If the hidden nests had too many eggs, I usually let them sit. Other wise, I rounded them up, cracked them into an "egg cup" (glass custard dish), and if they looked OK, I ate them. Or we did.
In cooler weather, I had a barn coat and when I went to the barn to collect eggs, I put them in the pockets of the barn coat.
One autumn day, late September, I put on my barn coat for the first time in a couple months or 3 or 4, and I went out to the barn. As I was sliding the door to the side to enter the barn, there was a huge loud sound, like a gunshot or a bomb and then a terrible smell!
I had accidentally left an egg in one of the pockets the barn coat ALL SUMMER in the heat! It exploded and smelled horrible. I threw the coat into the lake (I was living at Beaver Lake then). Later I hosed it off. Then I washed it many times and never completely got rid of that terrible smell. I finally abandoned that coat!
