In Ferndale/Detroit, yesterday and today are hitting temperatures in the high 90′s with around 70% humidity. The heat is oppressive, to say the least. I’ve been staying indoors in the cool air conditioned climate as much as possible, but the chickens don’t have that luxury. The temperature sensor in the coop read a whopping 100 degrees at noon yesterday, and the ladies were hanging out below it, panting hard and keeping their wings away from their bodies. Buff orpingtons like these were bred in England, and are cold hardy- which means they’re absolutely not designed for this sort of stifling weather. Luckily, this should be the last day like this for a while, but if we continue to encounter temps like this, I have a plan.
We made a simple evaporative cooler for the girls that seems to have helped in a major way. I’ve been filling large bottles and jugs with water and freezing them solid- it makes your freezer run more efficiently to have them in there, and I’ve got them on hand to place in the coop run for the chickens to hang out nearby (not that they do, but even having it in the vicinity seems to help). To make it, we place a box fan a short distance away from the run, placed the frozen jug in front of it, and angled my hose set to ‘mist’ so that the water hits the frozen jug and gets blown toward the run. The cooled vapor travels into the shadey area under the coop, where the chickens like to hang out- I can FEEL that it’s cooler down there than it is in the surrounding yard.
Best of all, the chickens don’t seem to notice it too much, and just hang out under the coop as they usually do. Yesterday, during intial setup, we discovered that they would NOT hang out in the shade under the coop with the fan directly against the runs fencing- it was just too new and scarey for them, and despite the heat they were standing in direct sunlight away from the fan. Once we moved it away and behind some plant life, they went right back into the shade. Care also needs to be taken to not spray too much water into the area you want them to hang out in- they’ll avoid having the water hit them.
In addition to the evaportive cooler, I added some “Sav-a-chick” to a giant metal waterer and placed it down in the run (rather than inside the coop itself). It’s basically gatorade for chickens, helping to keep them hydrated while they’re panting and losing water through their heavy breathing (this is primarily how they cool down). They each drink roughly .5 liters of water in the summer; you want to keep them stocked with water at all times, and keep the water cool (ie. not out in the sun). Drinking cool water will decrease their core body temperature, and having the “chicken koolaid” mix in there will reduce their need to drink, avoiding any potential “water toxicity” issues (unlikely to happen, but possible).
I also put out a shallow dish of water that they could stomp around in, but they’re avoiding it like the plague.
We’re also being mindful of what they eat right now- greens and cool fruit are a better choice, and care should be taken to avoid cracked corn and corn products, as those will raise their core body temperature (so keep it handy for winter!).
In the event that they show signs of not being able to handle the heat even with these precautions, I’ve got a tent set up in my basement that I’ll move them into. I’m hopeful that it won’t come to that, since I’m sure the change of scenery would stress them out only slightly less than the extreme heat.
