Thank you my friend, I bought a little Giants air forced incubator and I have the temp set at 99.5 and I need to know the safe range of control it has dropped two degrees and has risen .3 degrees the humidity range fluctuates from 57%to82% my elevation is 1421. Ambient temp out side is 57% the ambient and the ambient temp is 70% at the location of the incubator and I do not know the humidity level? What is a safe range? Will this fluctuation cause any defects, bowing of extremity's, legs toes wing's etc.? Thank you for responding my friend
