It depends on the quality of the strain in my opinion.. It would be interesting to know how many chocolate coloured eggs they actually lay.
Same here .I would also be interested to know if any that are laying the light browns lay darker eggs in the beginning of their laying cycle. Then get lighter. Or light brown eggs and then get darker. What I have experienced with my BCMs is eggs that do both . Also some just start with the dark color just on one end and then as they lay more they paint the egg all the way .I find that every thing about Marans is interesting. The black gene of the BCMs is super strong . I have crossed them with Gold Laced Wayndotts and every chick comes out black with the GLW rose comb and clean legs .Breeding back the pullets to the BCM the next generation they then have feathered legs and the combs are distorted and the eggs darken some more .I'm just a what will it look like breeder . I keep two small flocks One pure bred BCMs one with both pure BCM hens and GLW hens And a pure BCM rooster . Just finished a grow out that will have to be kept to themselves . I want my BCMs to stay pure .
