Describe your male, is he fairly dark. Is one of your hens not as salmon breasted as the other? Just curious, really don't know a thing, but was looking at the genetic eWh of a cream colored chick. Need someone else to make sense of it. Pretty sure legbars are e+, so how do you get eWh?
Above are the typical e locus down patterns, without columbian-like restrictors (except maybe ebc chick- Db). Columbian (Co) will change the appearance of e+ & eb down (usually adds eumelanin pigment, particularly on the back), but not E, ER & eWh (although eWh with Co are changed to a buff colour if sex-linked gold is present, but remain cream if sex-linked silver). Both E & ER down are indistinguishable, with variation from all black (eumelanin) to black with white as shown above.
The E locus is important to learn with poultry genetics. The common E locus alleles are:
- E (Extended Black) –black/cream day-old chicks, adults predominantly black, but may have some pheomelanin (silver or gold) areas in hackles.
- ER (Birchen)- black/cream day-old chicks, adults predominantly black, but may have more pheomelanin (silver or gold) areas in hackles, wing bows, etc.
- eWh (Dominant Wheaten)- cream day-old chicks, adult male Black Breasted Red, adult hen wheaten.
- e+ (Wild type) – dorsal stripes & eye stripe- day old chicks, adult male Black Breasted Red, adult hen salmon-breasted.
- eb (Brown) – brownish day-old chicks, adult male Black Breasted Red, adult hens brown breasted – stippling.
The E locus alleles produce the base primary colour/patterns to which varieties are build upon. The e+ allele is the wild -type, and produces the typical Black Breasted Red male- salmon breasted female phenotypes (as found in the Red Jungle Fowl, etc). All male phenotypes, except E & ER, have the Black Breasted Red colour/pattern.
