The latest in the weird eggs department...a lot of people call these 'Wind Eggs', other people cut right to the chase and call them 'Fart Eggs'. I refer to them as 'Hiccups'.
When I first found it in the coop I wondered who in Hell had given the chickens a peanut.
As usual with these, when broken open it was comprised of thick albumen and not much else.
Looks kinda painful, though. I've found tiny eggs before but never one quite this shape.
