We just started our first group of Black Copper Marans chicks. They are about 3 weeks old now, and there is one that is clearly a roo. He had an orange spot on his head as a chick, so I picked him out of the day old flock so I could have one to name and know which was which, haha. Since day 1, Rusty (the roo chick), has been more forward and curious than the others. His comb has become much larger and red in the past week or so, so I am certain he is a roo... not to mention that forward personality. I am interested in the personality evolution in roosters, particularly Marans. He walks up eyeballing my hand or whatever is within reach, and I always move before he gets a chance to peck... but he has that look about him. I am a bit nervous he is going to be aggressive. We will see - any thoughts? Can I correct this?
