I'm looking specifically in the difference of Ameraucanas and EE's.
I've been wondering the same thing. A few people told me my mille fleur bantam cochin rooster was SQ, beak colour and everything. I was like 'beak colour? That's part of it?'
Subscribing to see where this goes, I'm curious about the whole beack colour thing. My chickens seem to have a pretty concistant beak colour depending on breed...
Most breeds are supposed to have a beak color that corresponds with skin color, either white or yellow. And it's usually supposed to be solid, no black coloring. Some breeds should have all black, with no 'color' leaking through. It just depends on the breed.
For example, Barred Rocks should have solid yellow beaks. Mine all have at least some black.
Those don't look like any of the recognized colors for Ameraucana. If no color is specified at time of purchase, 99% of the time they will be Easter Eggers, especially if they are hatchery sourced. Ameraucana breeders are very proud of their birds, and will let you know exactly what color variety you are buying.
