The "leafy" comb as Jan so aptly described, is an indication of a single comb influence, it will get larger as the bird matures and he will pass it on.
The TYPE is really the number one concern and Temperament second, everything else should come after that.
Color is difficult to judge on the computer screen, but if the parents are Black over Splash, you have done an
outcross, since each color Black, Blue and Splash are a separate variety and should be bread separately.
I broke that rule this year, as I wanted to hatch a bunch of Black pullets so Crossed Blue over Black, colossal mistake because of course I got 1 Black pullet and 5 black cockerels.
But that kind of outcross brings with it some pitfalls and lots of culling has to follow.
One of them is a "dark blue" with almost a brownish tone, which isn't really dark blue it's more of a very dilute black.
I have already got my Blue keeper separate so couldn't take pictures of them beside each other
This is the "brownish Blue" cockerel, although very good comb, heading for the freezer...
This is the "cool Blue" cockerel, kept back to see how he fills out at 5 month....
