So check it:
General Lee when he was a very young cockerel:
General Lee's line bred sons/grandsons/great grandsons:
#1. Almost exactly like him, except for greenish legs and a different comb.
#2 Again, slightly different comb, but otherwise spot on.
#3. This is my hopeful breeder. He has the required red ear.
Now that the genetics are concentrated, more offspring are coming out looking like the progenitor of the line. The main difference I'm noticing all of the most of the new offspring have wrap-around combs more like Number 1 (my archetype Cracker) instead of having Lee's comb that stands off from the head more. But otherwise they're starting to look more like spitting images.
The next step is to grow them out. For the time being, #3 is in the coop with 5 pullets and 1 mature hen from my teacup Cracker line. Remember the teacup Crackers are of the same stock as these that I split off some time ago. These are the closest relatives I have that survived the Marek's outbreak without symptoms that are distant enough away to not likely have immune issues upon breeding.
As junglefowl hybrid pullets, these look great. Contrast with the sisters of these AGB line-bred stags off of Lee:
Similar, but the AGB sisters look more like OEGBs than RJF hybrids. Those sisters are going to the teacup project so that each project takes a break from close inbreeding for a generation. Both the teacup brood and the AGB brood are the same ages within a week (mid-late March hatch to my recollection). And yet the AGBs are already laying.
