My chickens are 15 weeks old and I live in central Indiana. The heat indecies are in the low 100's for the past 3 days with a welcomed break coming hopefully tomorrow. I was reading on another thread about feeding frozen treats on hot days (which I have been giving frozen watermelon) and their nutritional needs. The thread I was reading said, and it makes perfect sense, chickens don't eat as much when it's very hot. When you give the frozen treats that's all they eat and don't get the nutrition they need which causes a whole host of other problems. So here's my idea. Let me know if it's ok to do this. Make a mash from their feed and refrigerate it or even freeze it. Will that cause a problem with the nutritional values?
