You might remember I made the mistake of putting 4 eggs in the incubatoer 8 days after putting the first batch in. Hatched 4 out of 6 last week and after high humidity and not turning these 4 I thought they would die. Since I saw movement after the first hatch I lowered humidity and started turning again. Went into lockdown on Monday evening and 2 are pipped tonight. One is almost zipped, but one has pipped the small end and done nothing else for 3 hours. Is that normal?
