Hi folks. My wife and I sat 35 eggs at approx. 4pm Apr 1. On Apr 11, I candles and culled 9 unfertilized leaving us with 26. On Apr 19, we hear one peeping, and we have a chick by 4pm. The rest started to hatch on the 20th. Now we have about 20/26 in the incubator hatched out, with a few more pipped. I have been busy with the side business and my regular job, so I have not been monitoring the temp/humidity as closely as I did the last time I set eggs. I know the humidity has fluctuated between 20-80% depending on when I added water, and the temp between 98-101*. Could the fluctuations in temp and humidity caused some to hatch early? I thought 21 days was pretty consistent with chicken eggs. I normally count the day I set the eggs as "day 0" and was anticipating the eggs to hatch on the 21-22 of April. Should I count the day I set the eggs as day 1?
