I have teenagers that I have been keeping in a separate pen in my main coop for 2 weeks. Is 2 weeks a long enough "training" period for them to know the main coop is where they should now roost at night? or will they attempt to go back to the "baby" coop? Should I leave them locked up for another few weeks before letting them out? (I do have a fan on them since losing one to the heat. Although they do have good ventilation and there is a good breeze, (when we get one) going thru there, the fan has made a huge difference.) With my original flock, I kept them locked in the coop for 6 weeks, but that was because I had guineas I wanted to "train." I'm hoping I don't have to keep these girls locked up 6 weeks? Thanks.
