I have two groups of chicks. Group A and Group B. Group A is now 10 weeks old and were/are hardly fed treats-- just this week were put into their coop. They don't peck my hand ever-- they do however show interest in my rings, but no big deal. On the other hand, this group is much more shy than Group A. I put my hand near them and they run I hope they like me someday? Group B who are 3 weeks old now, get more treats as I have discovered through BYC that is the way to their heart and they are still in the house with me. Group B is also MUCH more aggressive. When I put my hand in the brooder they peck at my hand, fly trying to get out and are just much more active. Running around going nuts. Anyways, my point is- will Group B, the ones who have been receiving treats be so aggressive forever? I don't hand feed them the treats- I just put them in the brooder and watch them go nuts. I even put my hand in there and they all go nuts pecking me. Doesn't hurt, but as they get older will it? Also, will Group A ever decide to come around and quit being shy? Is food the only trick to helping them not be afraid? I feel like I have messed up. One group I didn't give enough treats to and now this other I have created monsters. LOL!
