So I have 11 chickens that are just about 7 weeks old. I just finished the coop/run yesterday and put them in last night before bed. All seem to be doing fine. But the little gal of the group I thought was a slow grower. But today all the feathers are missing from her back with little blood spots. So I separated her from the rest. Back inside in the brooder. But my question is this. How long can I keep apart without creating problems? I want to keep her apart for a bit for feathers to grow but how long is too long.
