We are in a position where we have 5 roosters of differing ages, between 6 months and 4 weeks. Right now, with 2 of them maturing, we can already see that we're going to have issues. Knew that, but wasn't ready to make the decision yet. The oldest 3, including the 2 maturing, are mixes. 1 of those is a really great rooster, the other is probably going in the pot. The 2 youngest are pure breeds, a Black Copper Marans and Golden Laced Wyandotte. I have various pure breed hens, and I'm trying to look down the road at what mixes I might get. My question, is if the Marans Roo will likely breed darker eggs than whatever the hen is. For example....will the Marans crossed with a light Brahma result in some pullets that will lay darker than the mother hen? Also, will the Marans Roo crossed with a blue egg laying hen have a chance of resulting in an olive egger?
