I sit in my cage w/my chicks almost everyday if I have time. One "red" seems to have adopted me already. She'll jump in my lap & sit for the longest time, getting rubbed & petted. Several others will sit for shorter times. What I have noticed recently, is all of a sudden, one hen or another will zoom down on a loose feather & scarf it as if they were starving. I have seen them eat a loose lying feather(s) amost 2" in length!!!! Is this a signal I don't understand?? Has anyone seen thier chickens doing this??
