I'm here in SE Arizona. The temp is in the triple digits. I've been told not to give the chickens scratch during the day due to the heat generated by the chickens in digestion. My problem is that they don't want to eat the whole oats or lay pellets that I give them. They free range over 1 acre of desert ground. I also give them what ever scraps/leftovers from the day before when I feed in the morning. The coop is in an adobe barn that never gets cool. Temp at 10 p.m. is still in high 90's. If I give then scratch in the evening, will they stay hot all night? I'm afraid that if I don't give them scratch that they won't have enough to eat.
