Thanks again Don and Vicki. I appreciate you both.
Don, I think the single matings are going to tell me tons. Oh was going to say...I have access to a Splash Copper hen...egg color needs work, she is from Bill, my old dark blue large male and the same females that produced that the Blue Copper hen. She is just as large as the Blue Copper, has better shank and toe feathering and if memory serves correctly, when I saw her the other day she did not appear to have the same high rear end. I gave this Splash pullet and 2 dark blue copper pullets to my bestfriend for Christmas a couple years ago because she wanted babies from Bill Sr. Both of the dark blue hens she has are very dark and show no copper, but I don't like them enough to use them. I do like the Splash and best friend has offered to let me have her back to rebuild.
Coming from the same lineage as the Blue Copper hen, would she be worth single mating too you think?
