I think the two terms should be mixed use. My opinion.
The SOP will be helpful to you.
I would want to know who the larger more mature birds were at this point, but only for additional consideration. In my start, I would not want to lose anything I needed moving forward. They are a sum of their parts, so I would be looking for those pieces and parts. That is the way my brain works. I would want to know what I had.
Knowing what I do know, and what I do not know, I would raise them all up. I would evaluate them once they had finished and could see what I had.
You may see some vigor between mine and her birds. That may explain rates, but is not solely and simply inheritance. I would not want to disregard one that was not a cross for that reason. Then my birds did average larger, but were oversized. Hers was large enough. I would even say that mine were too large. Then it was my opinion that some of her birds had better color. If they were smaller, but big enough, and had better color . . . I might want to use him or her.
Do you see where I am going? I am saying raise them up and let us see what advantages and disadvantages you might have. Let's see if we can put together a couple pairs or so together that might give you a good start. It also would not hurt to a couple that were the two of our birds crossed, and a couple that were from me etc. That variability might help moving forward. I was needing some variability to make more progress with color.
Next year is a different matter. This year is a start.
Let me say this. If your birds tend to be oversized at maturity, you can spare some size. It may not hurt you to use a good typed bird or god colored bird with less size, providing the bird was large enough.
Ok, I am understanding what you are saying.
I can't thank you enough for the help you have given me. I get down to North Carolina often, I may have to make a trip a little further south and purchase some refreshments.
