Im freaking out right now!! I have an egg that is 2 days older than the rest. While the other's hatch date is the 21st, this one's is the 19th. When we started incubating, we olny had this one egg. 2 days later we added 17 eggs and a large incubator (we have since thrown out 2). I didnt think this one had a chance of hatching. This was because, in the small incubator that it was i before, the temp spiked to 109 and 115!!! I thought the high temps killed it. But, i later found out it was growing!! I just candled today (day 14 for the others, but day 16 for this one) and the egg was completely black, which means it is fully grown. I was thinking that maybe, the high temps spiked it's growth instead of killing it. If this is true, im thinking the chick could hatch any day now! I was originally going to put them on lockdown at the same time, but now i dont know what to do!! If it starts hatching before the others, i wont be able to turn the others!! I dont know what to do!! Im panicing!! HELP!! WHAT DO I DO?!?!?!?!?! EDIT: I have an 1 that was set on the 28th, 10 that were set on the 30th, and 5 eggs that were set on the 1st. So, should i lockdown on the 17th? That would be 1 day after the oldest one's time, 1 day before the majority's time, and 2 days before the other's time.
