I am hatching a batch of 30 Silkie eggs. They had been on an automatic turner until day 18, they had the right temp and humidity. We candled the eggs throughout the incubation and they were all fertile. They have been on lockdown since day 18. They were chirping last night, and two have hatched today, with a few more pipping. The other eggs have no movement. What should I do? Just wait and see?
