My 3 chicks are 9 weeks old. They have now been outside for 1 week. I started by locking them in the coop at night, going home a lunch time and letting them out in the run during the day, which is 1/2 wire on all sides and top. Last night I purposely came home after dark to see if the chicks would go up into the coop on their own. They did not, they were huddled together in a corner of the run. How do I get them to go inside at night? The run is not safe right now, but I do intend to dig deep down and attach 1/2 wire to the entire edge of the coop and run, for the occasional extended weekends when I don't come home. I did read in the beginning it is best to lock them into the coop for a week or more 24/7 so they learn that is where they go at night..........I haven't had the heart to do that, is it necessary??
