Long story short I had a run in with a turkey nest and a tractor. 4 eggs are perfect. 4 have cracked shells but the membrane is fine. So I bought an incubator and put scotch tape on the cracked ones and they’ve been in there since Friday. Do the cracked ones have a chance? Or should I take them out? I was told they might explode? Anyways I candled the 4 good eggs and I saw movement! So what stage of life would this be so I know when to tell my incubator when to stop rotating the eggs?
