My little hen has been in the house for about six days now, but has been outside for several hours each day. I finished her small, makeshift run yesterday, and placed her in it last night. She took right to the nest box and i shut her in for the night. I am in Mississippi, and it gets really hot, so i have water in the nest box as well. When i opened it up about 6 AM this morning, she hopped right out and was fine. About two hours later i went back outside and she was on the ground, wings spread out and panting like crazy. I rushed her back inside in front of the AC and gave her MORE water, and after a few minutes she was up again and following me around the house. Her run and nest box are FULLY shaded, both naturally and artifically. She has a small kiddie pool half full of water, plus two water supplies in her run. I do not understand why she is overheating, and how to prevent. She is young now (11 weeks), but i cannot keep her in my house forever. I love the little hen like crazy, but i do not know what to do or how to prevent this... can anyone help?
