Sold as EE, guessing genetics

[kellylake01]

I was sold 3 pullets and EE, they look like they were part polish and barrel rock maybe, any guesses would be welcome, I'm rather curious if anyone has a better guess

Crest is probably from Legbar instead of Polish. Legbars lay blue eggs so they could be used to make EEs

Could be an Olive Egger with Cream Legbar (where the crest comes from) as one of the parents.
