The shortened version is this. I have 2 Buckeye hens, 1 of which had just been broody but not successful in hatching out eggs. They are also in with some bantams and some of this summers TSC Brown egg Layer chicks, that are about laying size at this time. During the time I've had the Buckeyes, they've never given me double yolks and usually have a normal shape egg with dark brown color. The last two eggs from that pen have been a lighter shade of brown and more oblong shape. I had one this morning and it was a double yolk. So, my question is, could the first eggs that a new hen lays be a double yolk? Or does a chickens eggs shape and color change over time? I believe the hens I got from TSC should be mostly Rhode Island Reds, Buffs and there does appear to be one Bramha. There is 1 white leghorn, but it's out since it will lay white eggs and these definately have brown tint to them.
