Lol I relayed the info. She asked, what does that mean?Sweetgrass
b1b1 cgcg
Calico
b1b1 cgcg nn Rr or b1b1 cgcg n- Rr
Calicos have the Narragansett gene and a single recessive red gene. Sweetgrass do not have either of those genes. The problem getting a Sweetgrass poult out of a Royal Palm or a Calico is that any male poults made this way will be carrying a hidden recessive Narragansett gene even though they are phenotypically Sweetgrass.
I answered, they look the same. But they won't always breed true if calicos, sweetgrass breed true.
