My daughter has always used traditional heat lamps, and waterers for her chicks after she takes them out of the incubator and puts them in the brooder...but her past few batches have been terrible, because the heat lamp will die in the middle of the night, the chicks will get cold, and die. She wants to try these for her summer hatches, because she plans to breed and sell chicks in the summer and doesn't want to experience heatlamp issues again. So should she get these 3 things? What reliable heat source do you use for continuous hatches? What do you recommend for chicks? Will heat plates stay on/safe/warm if they are on for weeks at a time? She also just needs your overall thoughts on how to have the healthiest/happiest chicks..?
