Another option would be to cross the Cream Legbar with a Silver Leghorn. The split would result in a Cream Looking bird. in the first generation and 50% cream looking if you brother sister mated in the 2nd cross. It wouldn't be cream. but would shed some light on what the "golden" color looks like with barring on it.it would be really nice if you did and did this experiment. i would love to have real word evidence of how they are effected.
this is an eye opener Ive seen these two things in my birds and others.
. With CLBs the contaminant is not as visual, but will be seen in the reddish or darker orange on the head, saddle of the male. And the females will have a brown cast to the body, especially on the wings coverts, instead of the grey-black back, wings and body.
And I was never really sure about the females, those with palest gold hackles were kept as CLBs.) Indeed some males had straw colored hackle and some had reddish heads tapering to creamishs ends of hackle or even the reverse, lighter at top, darker ends
