Dolly, the sheep, didn't lie.After re-reading all the advice I've gotten to improve shafting I've come up with my own personal game plan. I'm going to continue test hatches using different combinations, but allowing intermittent hatching from the same pair. So far, what I am seeing in my backyard, given my specific birds, is that even within a breeding pair some genetic traits are constant and some are random. I'm not seeing that the same parents are always producing the same chicks. So for now, I'm noting which are the constants and rolling the dice for the random traits. I am hoping that if the random traits are desirable and present in a pair, perhaps eventually that will become a constant. It's going to take several years to determine some of the genetic traits my birds have.
What I mentioned above is common sense to most, but I had to see it for myself I guess. The bottom line for me is: unless someone handed down genetic information about the birds you have when you purchased them, you have to start by seeing what you have first.
I guess I find challenges interesting.
