I just bought my third Nurture Right from TSC. I hatch lots of Silkie chicks, ducks, and turkeys to sell and have had pretty good luck with them. They are easy to use but you have to watch the humidity, as it fluctuates based on your home temperature. I like the built in egg candler and clear plastic sides. I read all the reviews and I’m sure there are exceptions, but I really like them.
I had a bigger one but there were several design flaws. The egg trays didn’t come out easily for cleaning and there were gaps on the sides of the egg turning trays that allowed the baby chicks to literally fall through the cracks. I like to leave chicks in the incubator for a day and it just didn’t work.
I prefer hens for hatching, but we have snakes and it is frustrating to loose eggs!
