All right Peggy-Sue! Yeah, with still airs, you want temps to be just a wee bit warmer than you would for a forced air unit. The range you specified should be great. I had good success with even at 102.1 with no ill effects. It had spiked to 103.4 at times & immediately popped up the top when that happened. Best of luck to you!I wish we had a broody! We are going round 2 with our LG tomorrow morning! This time we are going to try running it at 100.5 to 101... OUr two chicks that hatched this time hatched on day 23 so maybe with the warmer temps will get fluffy buts on day 21!
