I have used the still air little giant with a turner and it is good as long as the room temp is steady. I also have a genesis 1588 with a turner and it is much better at controlling the temps when the seasons start to flux and I don't have air or heat on. So cool mornings and warm afternoons.The only thing that worked for my dogs was heart worm pills. But it is expensive. On a different subject does anyone use a Little Giant Incubator my wife got one given to her with egg turner.
