My chicks are getting used to me. When I put my hand inside the brooder, they won't retreat. They will even chase it. When I rub their backs, they will not run away. But when I want to put them on my hand, when I try to hold their entire bodies to carry them, they will calmly look for what's holding them, then peck. I don't know why, but they just keep doing that. It hurts(physically). When I have to carry them(put them outside to play) they will still do that. So I put my grandmom to do it for me, and she can carry them, because she handles them very roughly; squeezing them too hard, carrying them on their necks. They're screaming/chirping violently. I pity, but they have to be carried. Please help. How do you carry them? Thanks in advance!
