I had to look it up. Here is what I found:
Origin of the Cream Legbar
The Cream Legbar is a cross between
Barred Plymouth Rocks and
Brown Leghorns, with some
Araucana and
Gold Campine genes. The Araucana genes give the Cream Legbar its funny little crest and the sky-blue or pale green eggs; the Leghorn contributed its excellent egg production (160 to over 200 per year); the Barred Plymouth Rock genes contribute the ability to easily tell roosters from hens when the chicks hatch.
So it is basically a mutt made up of 4 different breeds including the only two breeds I had understood were breeds - Leghorn thanks to
@BY Bob and Campine thanks to

I wonder if they will be crazy like the Campines or super friendly like the Leghorns. So far I would say both!
