    Ameraucana leg color or ear lobe color to determine egg shell color?

    When we candled the shipped eggs, we were looking for rolling air cells and twisted chalazae, just to give us an idea of how badly roughed up the eggs were. We use a homemade candler, which is an old piece of 4" metal ductwork with a compact florescent lightbulb on one end and the other end...

    Ameraucana leg color or ear lobe color to determine egg shell color?

    Sorry you had such a bad experience with shipped eggs. When my last batch arrived, they were so twisted around inside that you could see the twists when we candled them, and they all had detached air cells. We let the sit undisturbed for 49 hours point-down, then stuck them under a chicken. We...

    Ameraucana leg color or ear lobe color to determine egg shell color?

    None of the above. 100% of the offspring carry one blue egg gene and one brown coating gene, and would lay some shade of green, but not olive.

    You'll get 100% lavender EEs. Here's the lavender phenotype chart: https://www.backyardchickens.com/a/basic-chicken-color-genetics

    Ameraucana leg color or ear lobe color to determine egg shell color?

    Sounds to me like you're doing it right. If I lived near you, I'd buy EEs from you! I think YOU'RE becoming the breeder that you're looking for. As far as separating your hens, you're right. Separate for 2-3 weeks before introducing your favored roo. Doesn't matter if you remove the roos or...

    Ameraucana leg color or ear lobe color to determine egg shell color?

    Yes, I'd say this is the easiest way to make blue egg layers for you. (As ridgerunner pointed out, this is going to be very simplified) Most EEs from hatcheries seem to very reliably carry one or two copies of the blue egg gene, since the hatchery wants to make sure their customers get the green...

    Ameraucana leg color or ear lobe color to determine egg shell color?

    This is all true, and good information. When I said a "brown coating gene" it was a vast oversimplification. It reminds me of when I was in grad school, and the prof told us: "Everything you've learned about this subject to this date has been a lie. Useful lies, as they allowed you to learn...

    Hey, no insult intended. I used that link because I figured so many people of so many educational levels would see it and might be interested. Want me to pull out some of my molecular genetics stuff for you? Actually, the Mendelian stuff they teach in middle school is really all you need for...

    Ameraucana leg color or ear lobe color to determine egg shell color?

    Egg color genetics are far and away the easiest thing to understand about chicken genetics. The long lists of what's dominant and what's not also make my head spin, especially on feather color genetics. Here's a good explanation of Mendelian genetics at a middle school level...

    Ameraucana leg color or ear lobe color to determine egg shell color?

    EE roo from blue egg, heterozygous--assume w (white) and Bl (blue) genes OR he could have gotten a br (brown gene) and a white gene. If he got a blue gene, you'll get 50% wbr (brown egg layer) and 50% Blbr (green egg layer). If he didn't get a Bl, you'll get 50% brbr and 50% wbr, so varying...

    Ameraucana leg color or ear lobe color to determine egg shell color?

    First, they are Easter Eggers, since they came from a feed store and have green legs. I would guess that your lady with the white earlobes is a Leghorn cross, so her genetics are a blue egg gene X white egg gene, the blue is dominant so she lays blue eggs. Your other ladies with their red...
