Later tonight will make day 20 for my eggs, what should i be expecting? Idk if any are internally pipped because i have had them in lockdown since day 18 and I'm to scared to open the incubator and candle them because i don't want to possibly mess something up and they not hatch, i seen one wiggle earlier today, do they internally pip day 19, external pip day 20 and hatch on day 21?
