@Ch1cken Tender!
Oh goodness, I’ve hatched so many— both in incubator and under tiny broody. My experience has shown me, that days 20 and 21 are normal for all of my Serama hatches. I set incubator temperature to 99.5-100.5 (depending on incubator floor readings from digital thermometer/hygrometers). Humidity is kept at 45-50% for the first 16 days. Then I increase it to 60-65%. Many times in my smaller incubators, the humidity spikes to 70+ during lockdown, but that issue has never affected hatch rate. In fact, it’s easier to control humidity with my incubators exterior water fill chambers.
I lay the eggs on their sides and hand turn them an odd number of times a day (5). Incubators are kept in the warmest room, away from drafts, sunlight, and family members. I wrap large towels or small light blankets around them (not required, but I like to), avoiding the exterior water fill chambers and vents, vents kept between halfway to fully open (fully open during lockdown). I stop turning on day 17 for any possible early hatchers. I’ve had a very small number hatch before day 20, and those happened to be my few micro-class and required assisted hatch.
I use Kebbonix incubators just for the Serama eggs. They’re small (for 12 standard-sized chicken eggs) and fairly inexpensive, but this brand has given me excellent results. I also incubate small numbers— this is just what I personally prefer. I candle on days 4, 10, and 17. I always have an extra incubator running for quick transfer if 1 were to fail.
Of course, the best way to incubate Serama eggs is to allow the tiny hens to do it, because they’re incredible at it, and are wonderful, very dedicated mothers.
