I would like to make sure I understand.

An example.

Two Pairings of chickens:

F1= Red X Blue and Yellow X Blue

F2= The offspring: Purple and Green

Breed those two, and you get

F3= Brown and Bruises


Right?

P stands for Parental, the parent birds
F stands for Filial , F1 is the first generation, F2 the second & so on
B stands for Backcross, F1 mated to P gives B1

Not really, or it may be hard to understand the way you explained it. I'm gonna use breeds instead of colors to maybe explain it better.

Say for instance you crossed a RIR roo and Barred Rock hens, this would be the parental or initial cross, their offspring would be the F1s

Parental Cross = RIR X BRs
F1s = Their first generation chicks
F1 X F1 = F2

and so on

What if you mate an F1 back to a Parent? What would that be?

Yeah, this is where it gets confusing. I'd like to know too. Would it be B1? And an F2 mated back to a P would give B2?

But never knew what the 'F' stood for.

B1 [ back cross 1 ] . It was also used to designate a breeding back to the breed of one parent rather than the specific parent . If you're introducing a new color to a breed , then breeding an F1 or F2 back to the original color of the breed is a back cross , usually done for improoving type [*] once the color is established [ ETA : * without doing an inbreeding ] .
