So, my incubator that I am using right now, I think I am going to convert it to a hatcher...it is proving to be difficult to maintain temp in although is working ok. Any recommendations on an incubator that has a digital thermostat that is relatively inexpensive? Also, I bought an egg turner with my current one, are those interchangeable? Seems like all the foam bators are the same size and the turners all hold the same number of eggs...
