Are Cuckoo Marans a dominant breed? I have a brooder with three Silver Ameraucanas, one EE, and eight Cuckoo Marans. The Marans seem to be mean and very dominant. They will corner the other breeds and while standing in a semicircle, start to peck the other chicks. At first I thought they were all roos, but when looking up how to sex these chicks, I found that the roos will be grey while the hens will be black. Well most of these are black. I am now wondering if they are just a very dominant breed? And can chicks tell if they are of a different breed when they are all born together?
Maybe these chicks are just establishing a pecking order. They can start this behavior as chicks, I have seen this first hand in my brooders.
I do not believe that chicks know the difference in different breeds, but I have noticed that in older chicks and as they grow they tend to stick with birds of their same color. I notice this more in my Splash birds than the Blue or Black. My Splash pullets in a breeding pen of blues and blacks tend to stay very close to each other vs. mingling with the rest of the crowd. I have noticed that they will perch together on the other end of the roost.
I have 2 Blue Copper chicks brooding with my goslings right now and they pile and huddle right in the center of the goslings. Even though the goslings are 3x their size and almost 2 weeks younger the chicks don't even seem to notice the differences in species or size. The little cockerel is not afraid to let the goslings know who is in charge.
