I looked out back and realized that I had two escapees (8wk old Amercauanas)--had flown over the top of their run.. So, I ventured out to put netting over the top.. I decided since I would be out there, I would let all the chickens out and let them free range and took the phones, water and a book --ready to spend the afternoon out in my swing.. After I got the netting up and moved the swing into the shade and got comfy... I noticed my girls acting strange, coming out for a few seconds and then running back into the coop--not just the run--all the way into the coop.. I didn't understand. They LOVE to be out! I finally decided ENOUGH.. I locked the door to the enclosed run and noticed I had not turned their fan on.. I walked over and noticed a big black dog creeping up toward the back of the coop... SO glad I didn't keep running them out of the coop.. remember to listen to your girls!!
