Oh no, The owner name and website name is right above that picture. Justin Sorrell of Blue Poultry owns the Coronation Roo and Sussex Hen in the 2nd photo. (The Adults)

I should have tried to make that stand out better. I am going to go in and put it on the photo (so no confusion can happen, that would upset Justin and he a great guy!). I only own the Babies pictured in the first photo. The parent flock is Justin's Roo and Hen.

I think you are right on. Test hatches are probably the only way to know who is heterozygous. Maybe Amazondoc knows more about genetics than I do, but I didn't think that a bird that is truly a "split" (heterozygous) should ever show any difference in phenotype (even in down color) from a bird that is homozygous for the dominant trait. Wouldn't it have to be incompletely dominant for that to occur and then don't all incompletely dominant traits show a difference in the adult plumage? I am not sure of an example where they wouldn't. Maybe someone that knows more about chicken colors can think of one.

As far as the 1:2:1 ratio in the offspring, that is the norm when dealing with a dominant to recessive breeding (in the F2 generation). That would always be the allelic frequency, wouldn't it? Of course, that is basic Biology 101, so I'm sure most people here know that already. Again, maybe someone else that knows more than I can think of a situation when this wouldn't be the case. I think it should always be the case when the original pair consists of a bird that is homozygous for the dominant trait and the other is homozygous for the recessive trait.

Thank you so much! Justin (Owner of the Adult Birds shown) said that I should do the same thing. That is about the only way to tell. So, I guess my dear husband will have to build me some more pens

He'll really love that! Or, I could be nice and only keep the Coronation, which is probably what I will end up doing, since that was my main goal.

Congrats, Cammie, they are beautiful, and it won't take you that long to get your babies on the ground!

I'm not trying to bump heads or anything, but can you get more shots of the other bird inside of the feeder?

And congrats on your new purchase!!

I think if it was me, and I wanted to increase my flock of coronations, I would keep all the best typey females, reguardless of color. I would then use my best typey coronation male, or males, over these hens, producing coronation, or at least split chicks.

They were trying to get away from the camera is why they got into their feeder. But, which one are you wanting more pictures of?
