Is there a recommended number of days chickens should be confined to a coop and run before letting them free range? My pullets (approximately 20 weeks old) have been here now for 3 weeks. The first week or so they would not come out of the coop hardly at all. Now they spend more and more time in there run. I don't plan on free ranging all the time but would like to let them out for a few hours from time to time when I am home in the evenings. I am guessing at this point they won't wander off too far and will know where their coop is. Any reason not to let them out some this evening or should I give them more time?
