It's been a little while since I hatched, but if I remember correctly, I ran the humidity at about 40% initially and then 65-70% during lockdown. I will not incubate SFH and BCM together because they seem to need different humidity levels - the marans being lower (about 35%) initially.I dunno why I can't seems I get shipped eggs to hatch. Local eggs are fine.
I am PRAYING I have at least 1 of each gender, even though the three I have are at least half sibs and could be 100% sibs. The only variation is the shipping. I even let some sit and some went right to the turner of another batch, and none of those made it either, even though I got some local eggs at the same time, and they were nice babies.
I live very near DC, and they are security-mad around here. Radiation during the early stages of gestation is a known risk for miscarriage and birth defects; I'm very careful at work, especially after I had a baby with a birth defect that could have been caused by radiation exposure. But it doesn't explain why it's just me, because packages are radiographed all the time.
Could these be super sensitive to humidity? That is the other thing I am wondering about. Maybe they would do better if I tried 50-55% instead of 60-62%.
