I found 3 fairy eggs and 1 normal size egg in total during the first 2 weeks of the new rescue hens being here. Fairy eggs are tiny and yolkless eggs and are also known as witch eggs, fart eggs or wind eggs. They’re usually the result of a disturbed reproductive cycle or occur when a hen is coming back into lay after winter. A young pullet may lay a fairy egg just as she begins to lay for the first time but usually these first eggs contain yolk and are just small for a while before gradually increasing in size. As long as the hen appears to be healthy then there’s really nothing to be concerned about.
Both hens are growing new feathers now and taking a break from laying, which they thoroughly deserve.
