Marans cockerels don't show their true colors until at least 6-8 months, and some closer to a year. You can have a cockerel with perfect tail angle at 5 months that has a 90 degree tail angle by 8 months. They change so much as they mature. You can normally tell a lot about how a pullet is going to look type/tail angle wise by the time she reaches point of lay. A pullet's color is usually in as good as it's going to get by 5-6 months.
Marans roosters can have a difficult time keeping a large number of females bred. If your males are running with your layer flock, your Marans pullets may or may not get fertilized adequately because the males have too many females to service. If you have 2 roosters in a pen with your Marans pullets, there will be controversy as both males mature. There will always be a power struggle to be top dog. You only need one male per breeder pen. Plus you want to know which male sired your chicks. Also, two males means twice the mating which can wear on your females. I think I've been told that 3-4 females is a good number per male in a pen. Any more than that and the male may not adequately mate them all.
Also separating your males at this point will allow your underdog cockerel #2 to "cock up" and develop faster. Subordinate males tend to have their masculine features muted for longer in the presence of a dominate male. Their comb and wattles stay smaller and they may carry their posture/tail lower than they would if they were the only rooster.
