you can use either P1 or F0 to designate the parent generation. The F stands for Filial.

ABcDe wow that really confused me.

Well so what are birds a and b and c and d? I think the Fs are for the amount of times you bred back to the same thing. At least so I thought until Steve throws in P1 and B1's ect. I thought that if you crossed two lines and the offspring was f1 and if you then crossed the offspring back to one line.... say the male line... it would be an f2? But what Steve is saying is that would be a B1 if I would take an F1 and bred it back one of the original Parents (P). Is this correct?

Confusing. So Katy lets hear it.... what are your alphabets? I'm too lazy to dig through your 400 page thread....

I believe so , although it does not have to be bred to a parent to be a backcross ; in this instance the parent line would be a Buckeye . I actually never think or record in the abbreviated terms except for F1 and F2 ; and that's because when adding recessive traits to your line the recessive traits will not show in your F1s , but will start popping out in the F2s and even to a greater degree if you do a backcross of F1 to the parent line that displays that trait .​

With what you outlined here

ok so bird A x bird B = AB/ f1?
then AB X C =ABC/ F2
then ABC X D = ABCD/ F3
then ABCD X E = ABCDE/ F4

Its safe to call it F4 if you want to refer to how many generations you've got going into your line overall. Its probably not the most accurate way of describing it but it makes sense. The biggest thing is for you to be able to keep track of what your doing.

If you did this breeding (using your letters from above)

A x B = AB/F1

A x AB =AAB/B1 (A is the original parent) Your taking the original father (A) to his daughter (AB).

Same as B x AB = BAB/B1 (B is the other original parent) this would designate your were taking the original mother back to son, which is what I think was trying to be said when the B and P first came up. Ive seen that designation (B instead of F) before used that way.

Now if you went and did AB x C then its F2.

If you did AAB or BAB x C then it would be F3 The AB is the 1st Generation (F1), AAB or BAB is the 2nd Generation (F2 or B1 however you want to designate it), and the AABC or BABC is the 3rd Generation. (F3)​

I'm curious what were the weights at the 10-12 week mark on the F1? When will you have an F2?

 

[Brunty_Farms]

I didn't keep detailed records of this but from looking at them I would say they were about 5 pounds live weight. I'm working on the F-2 generation right now.... getting ready to start setting eggs.

Now the females are over 9 pounds and the male is well over 12 pounds.

Which is perfect....

 

[Jared77]

Is your F2 a father x daughter and mother x son breeding? Just wondered how you paired them up.

And your original cross was a Buckeye roo over CX hens?

 

[AshleyFishy]

They were a meatie 5 pound or boney? Are they fast developing or slow?

 

[Brunty_Farms]

Just as meaty as a broiler but not as fast. They have wide breast meat like a the broilers but the legs are longer.
