This is my first time trying to incubate eggs and I only put 4 in to start. Statistics won out and only 1 made it to day 18. I put it in lockdown on Monday and it's killing me waiting to see if this egg is going to hatch. I'm not real hopeful cause I had some varying temperature and humidity in the beginning but I still really want it to hatch. How long after 23/24 days do you wait before you know it's not going to hatch?
