Stan, I set my Breeding pens up a couple of months ago. One with the TC Boy, and 2 with the 2 Gilbert boys I kept. I have never had either one of the 2 Gilbert boys show me any aggression, and I routinely just reach down and pet them. The TC Boy is a different story. I have to keep an eye on him and even then he has come at me face on. If I turn my back on him it is a given he is gonna flog me. For a while I would just grab him, and pick him up while I petted and talked to him. It never seemed to change anything.
I just hatched chicks out of all 3 pens 2 weeks ago, and leg tagged all of them. I am not sure what this means but as chicks his offspring is easy for me to identify even without looking at leg tags, their down, percentage wise is much more Black than my Straight Gilbert chicks. It will be interesting to see how they grow out. On the TC boy I really liked his body type, comb not so much and since it got frostbite this winter it really looks weird.
