Recessive White Rooster, babies are blue?

If they're all blue it's more likely that he's splash under the white actually. But it would take more test breeding to find out.

The recessive white x lavender chicks turned out black, so he can’t be splash underneath.

Ope you're right. My bad. He gotta be blue then and just the RNG came out wonky.

now splash would make sense I think? Thanks

Nope. RoostersAreAwesome is right. If you got a black chick out of them you can't have a splash genetic rooster. It would always produce blues or splashes. So you just got an unusual number of blues from a blue genetic rooster.

I thoroughly retract my previous suggestion of splash. All it takes is one black chick to prove that theory wrong.

You guys are on a whole different level than I ... So very much to learn. Now I have to find out what RNG is. At least I won't have too many blacks!!

Possibly. But that’s not exactly what I was saying. If you breed a recessive white (two copies) to a non-recessive white, all the chicks will only have one copy of recessive white, which doesn’t show up.

Hmmmm. I was thinking recessive white would be ww and dominant white would be, say Wb (over blue). So my understanding was backwards I'm thinking? White from a leghorn is dominant over almost anything, but it's really Wb over, say an austraorp and you'll have black leakage.

Lol this makes me laugh. When this chick came, I thought he was a white jersey giant pullet because of his coloring. He was a freebie and had an injured leg from shipping. I made a hobble out of vet wrap and his leg healed. I realized later he was ameraucana, and much later he started chasing the girls. When the beautiful blue rooster I bought in hopes of raising a few blues died, I subbed in what I had. So my white ameraucana rooster named Jersey is blue underneath his beautiful white feathers. And this is why I enjoy these birds . Thanks all

It's not so hard. All genes come in pairs. Like two lights in a dark room.

For BBS it's really easy. IF both light bulbs are burnt out the room is dark. If you have only one working light bulb, no matter which one it is, the room looks blue. If both are working it looks splash. So it's like BB black, Bb or bB is blue, and bb is splash.

Now if you have a chicken that is black, you know both light bulbs are burnt out (bb), blue one is working one is out and on splash both are working.

A chick randomly inherits one of the two light bulbs from a parent. So if you have one splash chicken (bb) it MUST pass down at least ONE b. There's NO other option. It ONLY has working lightbulbs to give the chick.
So there's no physical way a chicken with bb can pass produce a BB chicken because one "B" has to come from a chicken that literally doesn't have one. A black chick can only come from a pair where both parents have a genetic B to give.

So here's an example. You can see the leftmost breeding is a bbXBb. The middle is BbxBb, the right is BBxBb. A splash can never produce a black offspring. Never.

Thanks ... I thought I understood this until today. Now to study the whites!!

Idk about dominant white, but recessive white is just as easy. It's the same idea, but the light has two switches, like a ceiling fan light that has a pull cord and a wall switch.

If either switch is flipped wrong the light doesn't come on. It takes both the pull cord being pulled AND the wall switch to turn that light on. You know how sometimes you flip the switch and go ??? why didn't the light turn on and then realize you gotta pull the cord too... It's like that.

So recessive white would look like;

ww - not white, doesn't carry white (both switches are off, room is dark)
Ww or wW - not white, carries white (either the pull cord or the wall switch is in the on position but not both so the room is still dark)
WW - Is white, carries white, must pass down one white. (The light switch is on and the pull cord and the room is lit.)

And then extrapolate from there, simple dominant genes look like

DOMINANT/DOMINANT - shows the dominant gene, must pass one down (Good example, blue in egg shells, OO)
DOMINANT/notdominant - Shows the dominant gene but may or may not pass one down (O/o in eggs still puts blue in the shell)
notdominant/notdominant - Does not have or show the dominant gene (a brown or white egg is ALWAYS o/o)
