RIR or Australorp egg?

[pioneergirl]

I went to my neighbors today and in his henhouse we found a giant brown egg it was way bigger than the rest of his eggs. He has all RIR's including his rooster and one Australorp ( I guess- she was a black hen). I wondered if the egg was big because of the breed (possibly Australorp) or if it was just a weird accidental giant egg. Is this one I should not try to hatch?

Is it a double-yolker?

Well I did some research on the board and I'm guessing it probably is. Don't think I want to try and hatch it.

My Aussie's eggs are not bigger than a RIR. Most times they are either the same or smaller. Eitherway if it is abnormally large I would not try to hatch it b/c it could have two yolks and I have never known anyone to have a good hatch from a double yoker.

Take Care,

the 2 breeds mentioned lay about the same sized egg. I have been getting LOTS of double yokers from my RIRs this summer, the Black Aust. were good about it too though lol

If its a double yolker, I would guess RIR.
