The hatchery marans that I have seen lay eggs in the range of 3 or 4 as opposed to good breeders who raise hens that lay 5-7 or above.
I'm glad to see some feedback from hatcheries.
Are you referring to hatchery Black Copper Marans vs. good breeder Black Copper Marans? Or are you comparing Cuckoo Marans eggs? Exactly which type of Marans eggs are you talking about?
