I'm panicking. I have 8 hens. I usually let them out to free range late in the day. Today has been one of the cooler days of the week (mid 80s) and their coop (and attached run) are in the shade. So I let them out and first, one laid down, laid on her side and lifted a wing. About a minute, she got up. Then they were all doing it--out in the sun. I've had them out in hotter weather and never seen this--out in the open, in the sun. Other points: they had significantly dropped egg production last week. Thought it was the heat. They have plenty of calcium and fresh water (and food of course). DE in their water to help with potential parasites. In the last 48 hours, we had 3" of rain--so they're not dust-bathing because there's no dust. In the hotter weather, I've never seen them dust outside of their run. Egg production is back up the last few days--but not back to normal. Hens were born a year ago Memorial Day weekend if that helps any. Of course, no clue what they're doing now as I ran in here thinking they were all going to die and posted immediately. ETA: Checked again... they all appear to be "normal" now and back under the fig--their favorite place.
