It's tough to see them scared. I adopted 3 young girls this fall who went through a few predator attacks at their previous place --they were survivors out of 8 in their brooder. I got them because they needed a place to go as this place for kids shuts down for the season. They had been with spent hens who were set in their ways not really allowing the young ones to eat/drink or be down off their roost. Needless to say that in their "grow out" pen they were scared all the time up on the roost during the day. Fall came and I quickly snatched them up. Introducing them to my Young flock was challenging even because they were SO scared. I tried to get them to interact and then just quit interfering and let them go at their own pace. It took a good 2 1/2 months before they would forage with the others who weren't even that tough on them...because they were so skiddish. All is well now and they've taken to my banty rooster who always defends them and looks out for them. He's ecstatic to have his own Harem of Girls!
