We're on Day 15 of incubation. Other than regular checks of the temperature and humidity, you're pretty much just leaving the eggs alone at this point. Obvious blanks should have already been pulled out, so unless you are seeing anything fishy on the surface of your eggs, there is no need to handle them at this point. Just sit back and let nature do its magical thing!
On Day 15:
- Beaks are hardening
- Leg scales and claws are hardening
