I love, love, love your golden cuckoo olive eggers!Mine seem to lay every other day. The darker the eggs=longer time in the reproductive tract getting their color. Marans as a breed are defined by egg color, so they will come with lower laying productivity inherant.
But what they don't have they make up with color:
These are from my line, as well as some golden cuckoo olive eggers.
My big beautiful boy now has his own girls. He has the CM hatchmate, 2 BCM's and a blue copper marans. He and the girls are quite happy. I should be able to collect eggs in another week to test hatch. Thank you @morbius18 for your generosity and guidance!
