I have nine eggs in the incubator due to hatch tomorrow, and two of them have already pipped as of this morning (24 hours early). I thought eggs were supposed to pip on the top of the egg, but these two have pipped on the side. The only time I've seen eggs pip on the sides or bottom was when an early-hatched chick knocked them around in the incubator but these eggs haven't been disturbed since lockdown. Any idea why they might be pipping on their sides instead of on the top? I'm supposed to turn them with the pip facing up, correct? Or should I leave them as is?
