Do commercial brown egg layers carry eb or e+ ?

[Aneury Sanchez]

Wanted to ask if a isa brown / hyline type brown egg layer chick has white back stripes does that mean it carries eb or e+ or is it based on pure wheaten like chicks without the stripes ?

I'm not sure but I think it's probable that they are e+/e^Wh. I am sure that the red parent is wheaten but the silver could definitely be duckwing based. And I have observed that black based DuckwingxWheaten chicks have some interesting stripes, so I think dominant white lines would be pretty similar.

They maybe e+/e^Wh, & e^Wh/e^Wh, since these are a cross breed bred for sex linkage.
They won't be both split, and pure wheaten at the same time of course that would be impossible with an individual.

The Sexlink line also has Columbian, Gold, & Mahogany(Red). The males would be Silver, or Gold/Silver Split, & Columbian.

Here's a link showing the variability of the chicks, both male, & female.

Here's a screenshot of what classic red sexlinks look like. Male, & Female.
