Shipped Eggs in Lockdown

[chonsey]

I have a dozen shipped eggs in lockdown, four have internally pipped. I heard one peeping. Day 20. Humidity 65. The other eight eggs may have malpositioned chicks in them. How long should it take for the four that have internally pipped to make an external pip?

They can take up to 24 hours to externally pip from the time that they internally pip
