Chickens can be strange little creatures when it comes to laying eggs. All kinds of odd anomalies exist in the realm of abnormal chicken eggs. Most of them are sort of gross to be perfectly honest. The exception to the “gross” rule are the cute little eggs, lovingly referred to as “fart” or “wind” eggs. Wind eggs are without yolks are also called “dwarf” eggs. Such an egg is most often a pullet’s first effort, produced before her laying mechanism is fully ready. In a mature hen, a wind egg is unlikely, but can occur if a bit of reproductive tissue breaks away, stimulating the egg producing glands to treat it like a yolk and wrap it in albumen, membranes and a shell as it travels through the egg tube. This is what happened in the Icelandic coop today. When closing up for the night, I found this in the nest box.
Here is the little egg, in the center between a normal Icelandic egg and Michael’s fish oil pill!
