In September I bought 3 little barred rock pullets to go with my little flock of hens. Two have disappeared, the latest last night. I'm not really saddened, but I don't want to lose any more. I have one of the pullets I bought left and I'm not letting them out of their coop to freerange in my yard. My first thought, is bird of prey. But my second thought now is that this pullet doesn't have any of her "sisters" anymore. Do they get lonely and go nuts w/o a friend? I'm afraid she's going to be a total loner, and end up banished from the flock to the point of starvation or easy pickings for another bird of prey.
