Happy to report that i just hatched 11 out of 13 eggs. 9 of them were cuckoo marans and the other two were light brown leghorn bantams. I just want to say that its not as difficult as some would have you believe. I had several spikes in temps, and humidity issues, but dont give up. When I first moved them into the hatcher, my temp spiked to 103.5 for at least 12 hours. They are in a forced air incubator, so i was certain they were cooked. I just lowered the temp, and waited it out. I kept the humidity between 60 and 72%. I did this by spraying water mist through the vent hole on top. It worked like a champ. Anyway, this is my second hatch and I just wanted all the newbies to know they can do it.
