So, this chicken is HUGE compared to all of my other chickens of the same age. Why is it so very big? Do you guys think it is a rooster? If so, is there any way it could possibly be a cuckoo marans? I ordered barred rocks and cuckoo marans from McM hatchery. I was supposed to have a cuckoo marans rooster. The rest were all supposed to be hens. However, I think I ended up with no cuckoo marans rooster and a barred rock rooster instead. However, this monstrous chicken does not act like a rooster at all. In fact, he/she is bullied around quite a bit. My chicks are 17 weeks old. Thanks for your help! In one picture, the huge thing is standing next to what I believe to be a cuckoo marans to the right of it. Look at the size of its legs compared to the rest his age.
