I do know this... the egg color shown in the hatchery catalog was no where near the color I was getting.
That would sting.
I had heard before I'd ever even heard of a Black Copper Marans that the Cuckoo eggs had lost their color, while the catalogs still listed them as "chocolate" layers. It was kind of like the catalog writers didn't ever look at the chickens or eggs that they were describing.
I do like how Meyer does now (2012-this is my first catalog of theirs) show photos of 3 eggs from the Cuckoos. They look like a New Hampshire egg. The photo of the Black Copper Marans, however, are 1 light, 1 medium dark, and 1 dark. So 33% are a pretty decent representation of a dark Black Copper Marans egg. Even the medium would satisfy me when comparing how easy it would be to order chicks and get them in the mail when compared with the struggle I went through for my Black Copper Marans (hatching eggs shaken up in transit, 2 separate batches, 6 weeks babysitting an incubator).
I was thinking that Meyer only started selling these in 2009, right? It was posted somewhere that they got them from a fairly well known breeder. I have no way to confirm it, so I won't mention the name. I remember there being some sketchy comments back then like, "How could Breeder X sell Black Copper Marans eggs to a hatchery?" Some folks were scandalized. Maybe rightly so, maybe not. I don't have a horse in the race, so I'm just an spectator.
I have no idea if the hatchery will be able to maintain egg color over the years, but what's to stop them from just buying more breeder chickens from the same breeder they bought from before so that egg color can be retained in their hatchery stock?
So to me, my abbreviated summation would be: Hatchery=a risk possibly for egg color, but easy logistics. Breeder=a risk for shipping eggs, but you can see the egg color that your hens hatch from. Trade offs.
I'm glad you finally got your dark eggs from the Black Coppers. I think the eggs are pretty as can be.
