Chel, are you sure you don't have a sneaky fence jumper, too? tongue If not, I guess somebody's got some "surprise!" genes! lol
LOL I think that it must be the "surprise" genes!! The eggs were in a pen that is completely enclosed and the only Ameraucana that I still own are bantams (little eggs) that are also in a fully enclosed coop.
The source of the genes appears to be a buff polish hen that I got as a chick. I'll try to get a picture of her to post. I never noticed anything unusual about her,
I just thought that she was a "bad" polish. I only acquired the buff chick to keep a lone tolbunt chick company and when they were mature, I just tossed the buff in to my sisters pen of misc. layers and never looked twice at her. I did use the buff laced hen to check the fertility of one of my tolbunt cockerels and noticed at that time that her eggs were blue. The gold laced pullet that hatched from that cross also lays blue eggs, so clearly there was some hanky panky somewhere in the ancestry of the buff laced hen.
I just went out to the layer pen to take pics and I can see that both of the blue egg layers arent just "bad looking polish", they have a much less full crest, kind of Elvis like, so they are undoubtedly carrying some ameraucana genes. LOL I should probably have looked at them more closely, but once an oddball pullet is dumped in my sister's layer pen, it is off my radar.
Perhaps a few more crosses with the tolbunt or the tolbunt/gold laced cock will bring the crest size back up and still keep the blue egg. That would be fun!
