I would mate them (brother/sister) but make sure to read my program on inbreeding so that you will know what to expect.

If you are going to make a family from this, check out my Founders Program

I might have misunderstood where you are at. Let me try again. lol.

If I miss the mark again, we may need to talk about on the phone. It might be easier that way.

So, I’m assuming we are talking about your Aseels. You already bred brother to sister (inbreeding). If the offspring are good representatives, you should start your line-breeding program by breeding the best pullet(s) to the father and breeding the best stag to his mother.

You can do another inbreeding program (2nd generation), but that would only be necessary if there is still much improvement needed in the offspring.

As far as your American Games, You mentioned you are already line-breeding them to the hen, and they are coming uniform. That’s good.

My question, did you establish multiple lines? Because, when you reach 15/16 or 7/8 you will need to do a line-crossing. This would require a separate line of the same family. If so, do a line-cross with the other line. If not, you have 2 choices. You can breed to another bird of the same family, but not from the same line, if you have one. Or you can do an inbreeding program (brother to sister) and then reestablish multiple lines within the family in the next generation.

If that is a problem you will need to infuse outside blood, which as dangerous to the line and should be your last resort.

You want to stay as close to the Founders Program as possible.

If I missed the mark, and you have more questions and answers, let me know. We can talk on the phone or through Facebook voice chat if necessary.

No problem, that’s what I am here for. If you ever feel uncertain or confused, let me know. It helps me to clarify me message and the material.
