What happened?

[Henriettta]

I bred a brown leghorn to a Barred EE, and the chick came out a light colored wildtype? What happened?
I really didn't expect this? I thought the chicks would exhibit faint barring, or be all yellow?

Who was the male?

 

[The Moonshiner]

Why would you think it would be yellow?
Is the EE the rooster?
It's always a gamble when crossing to a mixed breed. They are almost always not pure for pattern so you don't know what genes are showing and which ones will move forward.
