Can a serama rooster mate with a standard hen?

[Dawnclucks22]

A few months ago we got two seramas, one of which is a cockerel who is about 9 months. He’s started mounting the rest of our 7 layers, but the Australorp is his favorite. I’ve seen him try several times, but is it actually possible for them to mate successfully? I don’t intend on breeding but I thought it was funny.

Well they will certainly try. I had a English game bantam that had successfully bred with multi standard hens

Where there is a will, there is a way!

Yes. I've had bantams breed standards successfully.
