I've been worrying about the heat for 3 weeks here in Kansas. We have had the hottest temps in 30 years -- today it was 109 near the house. My indoor/outdoor sending unit was in a tree and said 106 at 11 a.m., but when I moved it to the window of the coop, it dropped 10 degrees, so my mister and shade cloth "swamp cooler" was working at that time.
My little girls (13 weeks) are in that coop and doing ok. They are panting, but I'm giving them lots of wading water in the grass (don't ask about the water bill) and they can go out in the yard whenever they want to.
My big girls (1 year) are suffering more. The Delawares are still laying, but today I thought I might lose one of them when she went into the 106 degree coop to lay her daily egg. I took her water in a plastic cup, but she wasn't interested. The Campine and EE are doing better than the others -- they are lighter feathered. The Welsumer is molting and taking it really hard. If it doesn't break pretty soon, she may be in trouble. The GLW is sort of molting, too, and she is just keeping her belly in the water. They have access to the yard, too, and an area with a mister. This is causing all the chickens to bond pretty well, so if they all survive, they will get along ok.
The big girls' coop was 96 degrees at 9 p.m. They have a window fan and other windows, but it is still HOT in there.
I gave them some ice cubes again today and they were all sitting on them like they were trying to hatch them. I'll do that again tomorrow.
I HATE THIS HEAT.
Yes, I'm worried for my girls. I don't leave after noon so that I can keep them in ice water and sprinklers. I'm hoping this will break a little. Tomorrow is supposed to be 10 degrees cooler, but they have promised us lower temps before.
