I just checked the thermometer on the coop porch, in the shade, and it reads 97. Why on earth are some of my free ranging hens laying IN THE SUN? They are laying down with one wing spread out to the side. They look dead, but they're not. There is shade all over the place, and lots of puddles and wet dirt under the bushes where they usually hang out, not 2 feet away from where they are laying. Can anyone help me understand this strange behavior?
