I have three chickens that are now about 17 weeks old. I got them at about 12 weeks old. They are in a small coop about 4x8 but only 3' tall. The coop is off the ground and they have a 15X15 size run with lotsa grass. Today they stayed out side the coop all day in the rain. At bedtime they came up to me and just looked at me like they wanted something. I put the food in the coop to keep it dry(usually its in the run). They would not go in the coop untill I made a trail of food up the ramp and into the coop...this still took a half an hour. I hope they are ok.
