Just keep us posted on them, Kathy. I hate these genetic puzzles! Guess this is a good reason to ID where each bird came from and keep track throughout their lifetime. I'm hoping you get that new line of Delawares going! That would be a great thing since the bloodlines are so very limited. You may have to hatch quite a few from Oliver's pen, though. If we see that Jacob, who we know for sure is Isaac's son, is definitely throwing dwarfs, seems that it's possible that there are several lines with dwarf genes running through them. I'd like to know that for sure. I feel like we've all been had by genetic leprechauns!
ETA: We thought we had this all figured out, but if we don't, I sure want to know it! The problem is that unless one parent passes on two dwarf genes or each parent passes on one gene, we won't be any the wiser. I have seen a different type of dwarfism, one that isn't debilitating like this one is, and it popped up spontaneously in a chick years ago when I had other hens; pn the outside chance that Isaac indeed does carry the gene, then anyone who has a hen mated to him that also carries one, will see those poor little weird chicks. So, we all need to know. Ike is currently not being used as a breeder, though I have one two of his babies here now, one pure Del and one with Riley, my BR/Amer cross hen. I am also no longer sending out eggs to anyone, but I'd still like to know, ya know? Kathy, please keep me posted, okay?
