I have twenty-five 2 1/2 week old meaties. They are outside in a tractor coop with heat lamps. I am wondering when and if I will be able to take the heat lamps off of them. The temperatures here range from 50's to low 60's (not much difference between day and night temps). Will they need the heat lamp the whole time? I have heard some say that they are "hot" birds and don't need as much heat as regular chicks; I have heard others say that since they grow so fast, they don't have the feather covering of normal birds and need more heat. This is my first go at meaties, so I'm completely new at this whole thing.
