I have a Silver Laced Wyandotte whose eggs I would classify as medium (don't have a scale, so I'm guessing). My two Gold Stars lay a large/jumbo and my EE lays a medium/large. What I've noticed, though, is that the yolks are almost all exactly the same size, it is only the albumen that seems significantly different. Does everyone else find that, or is my chicken weird?
I think that is pretty normal...unless your wyandottes eggs are significently smaller the yolks will be very close in size.
