I knew you knew.....;O)Yes, ma'am, I knew, LOL. All this wasn't going on in '58! hahhahhahahhaa
BTW, I love your new avatar..that's the chick that wanted to get back in the egg after its first glimpse of the real world right? LOL.
One other thing to mention....no one knows for certain what happened to Punnetts original flock of Cream Legbars, as I understand it. It could be that they were so in-bred, that they were not laying well and not reproducing well -- I guess the true terms are fecundity and fertility. Perhaps to save any genetics from the original Punnett birds they introduced some Barred Plymouth Rock - knowing that they could still retain the autosexing that way....and not having all the knowledge of Punnett - thus voila - olive eggs get into the standard. dunno.
