But if the air is moving it is helping with any evaporation of moisture - hence how the swamp cooler works. If it were me here I would have the fans on my gang, esp as the temps are all over the place - it's been high 80's and 90F, then like today 64F... I am freezing here, I got used to the heat and now it's darn chilly for me. Of course it's low humidity today and that makes it feel cooler. They cannot get acclimated to the high temps, so they are heat stressed when it gets hot.Lovely to see that! If we don't see babies forming when we candle this weekend, a local farm supply place is having chick days on the 8th. We'll get some for Eenie.
It's hot! Only 92 but the heat index feels like 98 according to my phone app. It's a bit hotter inside the coop. View attachment 3558821
But I'm happy to see that, in the nest box, it's actually a bit cooler (the thermometer has a probe I've put down there).View attachment 3558827
At how hot should I worry?
I have battery fans and frozen jugs of water ready to make swamp coolers if necessary. Making sure the run has shade and we can open the garage door on the front of the coop/shed for more air...but 106 degree air is still 106 degree air whether it's moving or not.
But I have to say the horses and chooks are enjoying this weather more, and the chooks are having a blast staying under my truck (it's parked here at the barn I unloaded feed and chicks) - they seem to be making a game out of going under one side and out the other side then around again hahaha. The Tweens and other chicks are pecking at the chrome on the mud flaps - silly birds

Even the horses seem happier, the good stout breeze is keeping the bugs away

You don't need to put any ice bottles out, just the fan moving would be perfect. 60% humidity is humid but here when it's humid its up around that or even past 75%, curtesy of the Great Lakes. I plan on using the ice bottles as an evaporative cooler (swamp cooler) next time it's hot here - I will keep the windows open to allow air to move helping with humidity.Gosh they don't seem distressed at all at 92. 80 is a really normal summer temp. Is your humidity low? It's 60% here. I wouldn't think adding extra moisture to the air would be a good thing...
I have two box fans in the Hen House for evening roosting - it gets pretty sweltering in there in the evening - our sun sets really high latitude wise, and it doesn't get dark till after 10pm. That's a lot of sun shining on the west and north side of my barn walls - and that is where the Hen House is located. I have it insulated but the sun beats in through the windows; I am going to put some awning/shade on those windows tomorrow if the wind is calmer. The other miserable thing here is the wind, after 6pm the wind dies down here all the time, wind here is dictated by the lakes - hot land during the day causes the air over the cold lakes to rush inland, but once that sun starts going down not so much heating of the land mass so the wind is reduced.
The poor chooks have absolutely no air movement so they and the my horses all have their box fans going full tilt. I love watching Henny Penny standing in front of it hahaha

This morning - very smoky
Chooks had a blast running amok
