On a very rare occasion, I find something weird. The little funny ones I save. Full sized ones just get eaten. Picture of a couple of "Fart Eggs", a long strange blob that is heavy and feels like it might be solid shell material, a bullseye marked one and a wrinkly one. The last two I think are from a couple of older hens that probably should be adopted out. The fart eggs are doubly funny because they were laid by really big chickens.
