We have a incubator that I purchase at Tractor Supply and purchased the additional turner. It is one of the styrofoam incubators. Our hatch rate in that one is terrible. What is it about those? What can one do to improve the hatch rate? We had a temp gauge and water. Or can you take an old cabinet and use the heat ring and turner and make a new one? I actually have two turners not sure if the other one works as I had loaned out an incubator and only got the turner back as they said they sat on the incubator and broke it. Any thoughts?
