I have 12 white leghorns & 12 golden comets, that are 16 wks old. As chicks, they were quite affectionate . My family compared me to the bird lady in Home Alone. The past 4 wks, the act terrified if I try to pick them up & they don't fly on me anymore. When I go in the coop, they all run out. I'm heartbroken. Any suggestions?
