My girls are about 6 weeks old and have moved out into their coop outside with attached 10' x 10' run. My intention is to let them free range an acre of property and garden during the day and lock them down at night. The problem is that even in the run they can't figure out how to get back into the coop at night. The last two nights they've been huddles in a corner in a pile waiting for me to pick them up one by one and put them inside. Obviously I can't let them out to play/scratch/eat if I can't be sure to get them back in and I'm NOT planning on chasing them around an acre yard to get them in. If I leave them out the fox will certainly get them all in one night. Will they learn on their own to go in at night? How can I help them learn this. Food treats in the evening? My other question is about weed killer. Earlier this year, about 12 weeks ago I used a Roundup type product to clear the paths around my vegtable garden. When do you think it's safe to let the chickens in there to to thier jobs and clean out all the slugs & grubs etc.
