I have a hen that only lays yokeless eggs... has anyone ever heard of this? It makes it easy when my wife only wants egg whites for a recipe so I am not complaining, just a little perplexed any thoughts?
I have no idea who her parents are. My two daughters and I bought her as a chick at an auction about a year ago. We bought four chicks and she was one of them. The other three hens lay perfectly normal. Good point, genetically, it would be impossible to mass produce them... lol. Her eggs are always much smaller, but have perfectly normal color and shape.
huhhhhhh.......that is so weird. i hope someone comes along and posts on here who knows something about what makes that happen........its so interesting.
Your girl has a problem with her ovary. The yolk is produced in the ovary and released down the oviduct where the albumen or egg white is added then the yolk and albumen are encapsulated in the shell glad or uterus. Since the egg is 'built' sequentially, it seems quite possible that a sexuallly mature bird that has a non functioning ovary could produce yolkless eggs.
Here's a pretty good website related to egg production in hens.
