Okay, I think I've got it now.As Jmns said, yes. To be a little more precise, each chick has a 50% chance of being Lavender. The others should all be black. It's a matter of odds. I'm trying to be careful how I phrase this. The pullet will have one Lavender gene and one not-Lavender gene. These will be passed down at random.
It's like flipping coins. If you flip a coin three times you might get three heads, three tails, or maybe a split. If you flip a coin 100 times you should get real close to a 50-50 split. Same thing with the chicks, the more you hatch the more likely you are to get an even split. With just a few chicks, who knows.
So if I mate the offspring of this hatch to the lavender roo, I'm likely to get about half blacks and half pure lavender color, not accounting for the leakage from the ISA Browns genetics.
And then, that will largely depend on how many eggs I hatch. The larger number I hatch, the more even the split. At lower numbers of chicks, It's kind of a crapshoot as to how many will be which thing.
Guys, I'm already getting so excited and I won't even be setting the first generation in the 'bator until a week from now! lol. And that doesn't even begin to mention what happens if I mix a rooster from this hatch back to an ISA Brown mom... a whole other rabbit hole to dive down, I'm sure! lol.
Also, as I understand it, leakage is mostly a bad thing that you should be culling out of breeding projects and purebreds... but I'm not gonna lie, I'm also excited to see how it presents itself as this hatch grows out into adults.
This is so cool!
