It went over 107 here today. *Last July it hit 117 a couple days in a row*
I finally got the AC in the coop going. I had skacres and his son from Marana here today and took them into my coop so they could feel the difference. They watched an Ameraucana lay an egg and took it with 29 others south to incubate. I need to caulk and insulate a bit more in my coop. I have a broody that's been sitting on golf balls for more than a week. If Laree has any extra Icelandic chicks, we'll be putting some under her to get her off of the nest.
I haven't checked on the marans or the icelandics for over an hour. They don't have AC right now, but I'll be building another coop for them during the summer. It's exactly 105 out there right now so the temp is on it's way down. It hit 67 here this morning so it cools down.
All of that said,
I would keep her on a damp COOL towel and Ice or a cool pack under the towel with the fan on her and mist her with cool water every now an then. It is fine until she starts to revive. Gatorade would be good for her, then if she starts to eat, boiled egg.
The last one I lost to the heat, wouldn't move her legs either... but one of the younger roos was trying to take advantage of her in her condition and that didn't help.
I've lost my fair share to heat stroke here. Dark hens seem to go faster than lighter colored ones. I've only lost one Ameraucana, 3 RIRs, a cochin-leghorn mix and a few polish to the heat
Good luck.
