e+ is wildtype. It is the original color of the Red Jungle fowl . From whom it was long thought all chickens descended until the Green Jungle Fowl and the Grey Jungle Fowl were also found to have participated in the origins of the domestic chicken.
Because of this idea of "origin", e+ is called "wildtype". The chicks are always chipmunked striped. In fact, the chick down is absolutely definitive for wildtype. It can only look one way and be correct. See here:
the above chicks are Golden Salmon Marans chicks. Golden Salmon is the French hobby name for wildtype.
Why is the chick down definitive? Because wildtype is a completely recessive color pallet. There are no other color genes, or modifiers. It is just e+/e+ ( copies of e+) and s+/s+ (2 copies of the gold gene in the male and one copy of the gold gene in the female which is written as s+/s- . There are no hypostatic genes in wildtype. It just is what it is.
Now Wheaten is a lovely color. The solid colored chicks usually are a yellow or cream color but can range from a light cream to a nice light yellow. Correct pure Wheaten is a solid color.
So when your chicks start showing a yellow ground color with faded or intermittent stripes , we know the chick is part wildtype and part Wheaten. Wheaten chicks would not have grey legs or beak.
