Ten days to go until hatch and we have 15 healthy, ohsosquirmy embryos! So far the ReptiPro 6000 has performed like a champ, holding temp & humidity like a dream, recovering quickly when I open it to turn the eggs 5x a day. Thanks to yinepu's advice so far, so good!
I even have three hens that have gone broody, we may recruit one of them as a mom for the chicks. Of course, one is a Giant Cochin, the other two tiny Belgian d'Uccles, just for comic relief--I can only imagine 15 rapidly-getting-larger baby chicks climbing all over a d'Uccle mom. The only problem I had was that my flock's large breed eggs all ended up not developing, which I discovered when I candled. I did an egg breakout and discovered them ALL to be infertile! I had forgotten one thing--this was their first full winter in a snowy, cold climate and my Giant Cochins and Brahmas had responded by growing tons of feathers, including enormous, hilariously fluffy butts.
So fluffy, my roo wasn't able to seal the deal.
So my kid and I, armed with scissors, went out and gave everyone a fashionably crew-cut hinder. One week later, viola, fertile eggs!
I plan on starting a second, staggered hatch this weekend. NEXT year, I'll know ahead of time to trim fluffy butts!
