The silkie eggs are on day 20 and were locked down at day 18. Humidity for lockdown at 65%. One pipped through the shell and I saw it at 7am although it may have been that way longer. It hasn’t done anything for the last 6 hours. Just a little hole in the shell. One other has some shell missing but the membrane doesn’t look broken through for about 4-5 hours. The other 8 eggs haven’t done anything yet. Is that normal?
