I just got 6 hens yesterday, they are about 20 weeks old. They seem to be adjusting to the new coop well, they appear relaxed when I go in and I even got a couple eggs already. I was told by the seller that I should keep them confined to the coop for about 3 days before I let them free range, and after doing some reading I saw that I should keep them confined for a week before letting them free range. How long would really be best to keep them in there? Ultimately I would like them to free range all day long but I don’t want to lose them so I want to make sure I do this right.
