I have a (actually 2) Little Giant still air incubators that I got for around $45 a piece. My first batch was fairly successful with 26 eggs hatching out of 36. My second batch was also
successful, with 18 eggs hatching (or something; I can't remember) out of 24. But as I did more incubations, I started getting lower hatch rates. For example, this past week I hatched only
3 eggs out of 51. I think I know what the problem is - low humidity, since I saw several eggs trying to hatch, but didn't make it due to exhaustion. I've filled all the trays up with warm
water, but the humidity wouldn't rise very much. I'm building my own incubator using the Little Giant heating element and thermostat, and adding a fan and bigger box, then adding an
ultrasonic transducer to regulate the humidity to solve this problem. Have any of you'll had this problem? Thoughts? Comments? I'm open to any suggestions.
