Is this a brahma egg?

Hi I have several breeds of chickens and most are just coming in to lay.

I know which eggs the RIR lays and the australorps.

However, I have standard brahmas and buff orpingtons and a wyandotte all sitting in the nest boxes, too. Most are just practicing and haven't layed yet.

A few days ago we got this odd looking egg from someone.
It is small, elongated, and rather pointy on the small end. It is light cream in color.

Who's is it? We are thinking it is a brahma, are we right?

Here it is beside a small australorp egg. It is cone shaped and more exaggerated in real life than shows in the photo.


My husband said, "It was left by one of the chickens that the Coneheads brought from their planet."
Coneheads from Saturday night live, omg!

Today, I found another one only much larger. It is longer than our large eggs from the Rhodie but much narrower and pointy.


So is this a brahma egg or an orpington egg? Will it stay in this shape or is this just the beginner shape?
How big of an egg do standard brahmas and orphingtons lay?

Thanks for you're help
