Any Polish chicken gene pros out there?

So tell me what this one is. Came out of a white egg on New Years Day.

It is either a White Crested Blue Polish X CA White Leghorn OR Blue Wheaten Ameraucana X Bearded Buff Laced Polish.

I can't imagine it being the first because that polish roo was rehomed on the 10th of November and I started collecting eggs on December 7th. but who knows?

Which cross do you think it is? and do you think it's a roo or pullet?

By the coloring I would say it is a Blue Wheaten Ameraucana X Bearded Buff Laced Polish cross. I am thinking a roo.

Are you sure this is not polish on polish or polish on polish mix? Crest seems pretty large for a crested x non crested cross.. It could easily pass for a Buff Laced and WC Blue cross from the polish colors mentioned here..


If this has to be a cross due to having polish in only one sex(?), one big clue is to look at comb. Leghorn cross would have a single comb, amer cross would have a pea. Polish are single combed combined with duplex, combined with the crest making it look all funny. My experience with polish cross with single combs were birds with much smaller crests, the single comb was obviously a single comb but 'funky' in the rear part. Crosses with pea made weird looking pea combs.

You know, there is the slight possibility of it being WCBlue Polish X BBL Polish. I hadn't even considered that!

How does it end up being WHITE???

Buff laced has dominant white. They're 'sort of' a Gold laced with dominant white added, turning the black lacing into white.. which is how dominant white works- it affects black pigments and mostly leaves gold pigments unaffected.

Buff laced x WCblue is essentially a cross with a black chicken.. black is also dominant, so it would throw black or mostly black chickens, except for the dominant white from the buff laced turning most of that black into white. The irregular black spots is very typical of dominant white x black cross too such as Leghorn x anything black(California Whites are White Leghorns crossed with Gray Leghorns, many of the resulting chicks are white with random black spots). It is possible to get mostly white birds with blue spots if it got the blue gene from the WCblue.

If Polish on Polish is possible, I'd choose that as the most likely parentage of this chick due to the crest size. Crosses of crested with non-crested usually produce birds around 1/2-1/4-ish the size of crest of the crested parent. Silkie x cochin crosses are pretty common, those would be a good picture comparison for the typical crest size of this kind of cross.
