My 7 little chicks, Welsummer, Barnevelder, Light Brahma, Silver Laced Wyandotte (2), Buff Orpington, and EE are acting very strange. They are eating and drinking great. But when I come into the room to check on them. They line up with their little heads facing the wall away from me. I usually cluck at them when I am coming in the room, so they get used to the sound. But, it seems they are terrified of me! I try to hold each one for a bit, a couple of times a day. They are usually pretty shaky when I pick them up, and then they calm down when I pet them and talk to them. I have seen pictures of Chicken Mom's letting the chicks eat out of their hands! Mine will not come anywhere near my hand even if I leave it on the floor of the brooder for 5-10 minutes. Help! I would like for them to be able to recognize me as a friend not a foe. Any suggestions?
