Sorry if this question has been posted before. This would be my first time raising chicks. So i wanted to know which heat source would be better? And with the EcoGlow 20 Chick Brooder can you set it at certain temperatures like you need to do with a heat lamp like have it at 90 to 95 degrees then as the chicks get older move the lamp father away so the temperature with be cooler? I hope a explained this ok sorry if anything is unclear Thanks so much!
