jhenderson, in the jungles chickens are usually in the shade. I have seen wild jungle fowel in the Philippines and they are most active in the early morning and move around quite a bit at that time. as it becomes warmer they find shade and stay in it. They may scratch and pick some but mostly it will be in the shade and not far from water.. The heat we have here is not humid . In fact its very dry but my chickens do most of thier eating early in the morning and stay in the shade the rest of the time. You could walk by my checkens pens at 10 AM and not realize I had chickens. At 6 AM theyare all outside.
