Staffordmum Posted October 6, 2009 Share Posted October 6, 2009 Has anyone ever experienced this? I passed on half a dozen to a colleague for a small "donation" only to find one of them was in fact yolkless. She was gutted! I Googled it :- Eggs without yolk are called "dwarf" or "wind" 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 has occurred if, instead of a yolk, the egg contains a small particle of grayish tissue. An archaic term for a no yolk egg is a "cock" egg. Since they contained no yolk and therefore can't hatch, it was traditionally believed that these eggs were laid by roosters. This type of egg occurs in many varieties of fowl. They have been found in chickens, both standard and bantams, guineas and Coturnix Quail. Fascinating ... Kind rgds, Pat & Steve Quote Link to comment Share on other sites More sharing options...
Plum Posted October 6, 2009 Share Posted October 6, 2009 One of mine laid loads of eggs like that but they were very small. Not heard of one that was normal size, guess she forgot to ovulate. Quote Link to comment Share on other sites More sharing options...
