My girls have been laying for two weeks now. Of my six girls, I've been seeing four eggs a day for the last four days (regular little egg factories). Anyway, of the eggs I harvested yesterday, two had little to no yolk (cholesterol free!), and two had a double yoke, one was normal. I guess it all evens out in the end! Their shells have all been nice and strong, and egg size seems to be more consistent now also.
