Hello all my fellow chicken lovers!! I'm new to the site but have been looking around for weeks. I have made an incubator this past weekend and have it almost perfect. My issue seems to be cold spots!!! I can't figure it out for the life of me so i figured i would come to the pros lol. The box is 21" * 11 1/2" * 10 1/2" I have a 60w bulb with the HWH T-stat that is drilled out within 1" of the bulb. i have a smaller pc fan blowing on the bulb& t-stat with a bigger pc fan in the opposite corner blowing toward the other end of the box.. There are 4 vent holes.Soooooooo can anyone look at this thing with a fresh pair of eyes and fill me in on what i might be doing wrong? Thanks so much.
