We have had Chickens since the 1st of may. We have 22 Hens, 2 Roosters and 2 regular? Guinea and 5 lavender guinea. They all grew up together some are 5 to 6 weeks older, but they live in the same Coop. It is 17x14 and we have about 14 laying boxes, although they seem to use the same 3 all the time. I was wondering when it would be ok to let them run around the yard, we live in the country and our nearest neighbor is across a ten acre field. There is a cattle fence next to the coop but it is only 4 ft high and we have not clipped there wings, so they could easily fly over it. Also how do you get them to go back in the coop at night. There are plenty of Owls, Bobcats and Coyote's in the area.
