For those of you who haven't seen it -- here is an interesting discussion on cream gold and silver. (Punnett).
Seems that the female is more likely to have cream and it is perhaps recessive.

He had thought of caponizing a rooster to see if this would boost the incidence of the cream coloring -- (or should I say colouring) --- I don't think he ever did... Page 330 is where the discussion is.
The section that niclandia was speaking to was the idea of multiple allellomorphic pairs of genes for silver and gold and then gold and cream. Gold has a sex link genetically. The conversation got bogged down with silver and gold and what is sex linked, what is autosomal, what covers what, etc.... I do believe that cream is 'recessive' and have some growing ideas about it's 'recessiveness' and links to gold and the male and female legbars but not clear enough to put into words. In the article above it tells you that you can look to the male secondary feathers to see if there is gold in the bird by seeing if there is any gold on them. The article discusses this and if you look at the pics in the back there are examples. This article is in color somewhere. I found this article a good one in helping me understand what I needed to look for,.If you look at a female that has a cream hackle vice a golden hackled female, the gold hen will have gold tips on the feathers that cover the entire body and that seems to also be a tell tale sign of gold in the female bird. I am hoping to have more solid ideas next spring once I start breeding again.I have seen this document before. And someone (maybe nicalandia?) was saying that scientist/geneticists did not correctly understand the way some of the genes worked and this section of his paper was incorrect? I may be mistaken but I seem to recall this discussion. Maybe someone else remembers and can chip in.
the recessive cream gene is an "Autosomal" gene, not Sex linked at all, Punnett was mistaken at the timeSeems that the female is more likely to have cream and it is perhaps recessive.

yeah that was me..I have seen this document before.

Oh so very sorry to hear this. What a heart breaker....I wish that chickens weren't so vulnerable. Sad news.
