I have 8 eggs in my homemade incubator. Today was day 22 and none have even pipped yet. Day 20 I saw a couple eggs shake but now nothing. On day 18 they all looked great. I've kept the temp at 102° throughout the entire incubation and humidity between 50-55% then raised it to 60-65% for lockdown. Is there any chance they may still hatch? This is my first time incubating other than one my hen had given up sitting on.
