Yeah, they will slow down on feed when it's super hot. I also don't feed scratch in hot months. My rationale is that the corn is harder to process, requiring more energy to digest, which means more heat generated. Is it a lot? No, probably miniscule all things considered, but when it's over 105 I look for every trick I can find to keep them cooler.Our girls have slowed waaaay down on eating feed. They get Scratch and Peck grower mash.
After we culled our cockerel we noticed a drop in feed consumption. I figured he had been eating a lot because he was a boy but that was about a week ago and the flock is still slowing down on eating feed, so it wasn't just him.
They gobble up any cold treats we give them but we don't want to give them so many cold treats that their nutrition is thrown out of balance.
They are 11-14 weeks old so this is their first summer. Is it that they aren't growing as fast? Is it the heat? I think we've been 100+ for about three weeks, if not longer.
Does your flock eat less feed during high temps?
Make them frozen salads. Shredded carrots, leafy greens, the like. Put some in ice cube trays or like a jello mold and freeze it. They get a cool treat and reasonable nutrition, plus they have to work at it to get it out of the ice. Watermelon is also decent. Sweet fruits in moderation. You can toss a few mealworms in your salad too for motivation.
