Buff Brahma× Opal Legbar: what would the female chicks look like?

[Ebz5003]

I hatched a gorgeous chick out of my Buff Brahma rooster and Opal Legbar hen, but the only downside is, it is a cockerel. He is so sweet and pretty I might have to keep him anyways. Pictures included. I am wanting to know what a female out of this cross would look like? Thank you.
