ok, you gals caught me...I MISSED a typo in the history!!!!!!!!!!!!!!!!!!!!!!!!!! The original quote by Professor Michael Pease is:
"An interesting new autosexing variety is the Cream Legbar. The cream colour is indistinguishable to the eye from silver; but cream is, for reasons given on page 2, none the less a form of gold. It may be thought of as an extremely diluted gold. The Cream Legbar has a crest, which distinguishes it readily from the Silver Legbar. It has proved to be a prolific layer; its most striking peculiarity is that it lays blue eggs. The sex-distinction in the downs is the same as that in the Gold Legbar (Plate 11c)."
(Pease, Michael M.A.,
Ministry of Agriculture, Fisheries and Food, Bulletin No. 38, Sex-Linkage in Poultry Breeding,
Other Varieties, page 8)
Page two just talks about the relationship between Silver and Gold, and reiterates that cream is diluted gold. So our history should not read that the crest distinguishes from both gold and silver, just silver.
Pease acquired all of Punnett's and his test birds when he moved on to other projects, so they are essentially the same.
@Nicalandia: Pease actually suggested breeding Legbar Roosters to Brown Leghorn Hens if you needed to improve or diversify blood line! It's interesting that you would mention that!
Edited to add: I love you too Kathy
