Variations from 2nd generation crossbreed

Thank you.
Yes, this Birchen Marans looks just like Fifi.

I looked up the definition of F1.
So what I'm calling second generation is really F1 ?.

your F1 x F1 are actually F2

Thank you.
So what would my Rainbow 75s be called by normal people?
They are purebred Dixie Rainbow hens X F1 rooster

Rainbow 75 alongside F2

I saw this pic and thought the bird's foot was deformed. I went outside to check it out and it's perfect. The camera must have caught it as the bird was running or something?

BC1, or Back Cross to Parent Line one.

On genetic breeding.

Parent line 1 = P1(Dixie Rainbow)
Parent line 2 = P2(Barred Rocks)
The cross of both Parent Line = F1 or Filial generation 1
The cross of both F1s together will be = F2 or Filial generation 2
The back cross of F1 to P1 will be = Back Cross to Parent Line one or BC1

Thank you!

I'm still gonna call them Rainbow 75s though.
I'm gonna call the white strain that look like Delawares ... Golden Rainbows.

I'm probably going to have to choose between my F1 rooster and a BC1 once they grow. Hard to keep separate flocks when you want to free range.

Any particular meaning to the 75s? Or why would you call a silver based birds "Golden"?

They are 75% Dixie Rainbow and 25% Barred Rock.
The Barred Rock are silver based but the caramel of the Rainbows is starting to tint some of the white chicks.

Half of the hatches are breeding true to the first generation crossbreed.

Here is a first generation Rainbow Rock hen alongside her mother.

2nd generation birds are now about 9 weeks old.
There is a black strain that is repeating in all hatches.
I was filling a water bowl and she came up and demanded attention.
She is a total lapbird now.
She looks all black when she is holding still but when she moves, an underlayer of silver shines through her cape. She's got a white tip on each wing.

There are some birds who look like a cross between Blackness and Fifi here.
Their markings are more subtle.

Someone who bought one of the six roosters I have sold is coming at noon to get more birds. Oh, you want pullets, I assumed. No, we want 2 more roosters.
This is crazy.

I just realized that I have never shown Waldo, the grandaddy of Rainbow Rock.
I felt so bad when I had to sell him to let Blackfoot take over the flock.

The first hatch is 10 weeks old today.
This guy is starting to look fierce but they're really pussycats.

Golden Boy, one of the white roos, has developed a lot of subtle barring.
He is sort of a Barred White

The white birds from my 3rd hatch are very different.
They are developing unique buff colored patterning.
I have to get a pic.

The black strain of birds are turning irridescent green when viewed in direct sunlight.
