Hi, I am new here. 1st time chicken guy. We have 2 rocks, 2 aracaunas, 2 golden Wyndolettes, and 2 buff orphingtons. We got them just hacked from a local feed store in April/May so they are about 4 months old. They have been outside now for 2 months in a coop and love it. My question is when can I start letting them out to roam? are they old enough? I have 8 acres of field that I live on and they are very safe - they would only be out when we are home. How to I get them to go back inside the coop? when it is time for bed? Will they go in themselves? I am just reluctant to let them out and then spend hours trying to get them to go back in. Any advice would be very helpful.
