I got 2 silkies about a month ago now from a person who told me they had saved them from very poor conditions, they had been kept indoors in a very cramped area. I now have them in our chicken coop which we open every morning for them to roam on our property. But they don't leave the coop ever, at first they both just sat in the corner and barely walked but once they settled in we cut their toe nails which were incredibly long. Then one of them perked up a little and walks out the door about a foot or two but that's it and the other still sits around and doesn't move much in the coop. Are these chickens too institutionalised to change to more free ranging behaviour or is it too late? How can I encourage them to come out more and scratch around?
