My due date was the 18th at 3:00am. Today I came home at 6m the 16th to find some already pipping. One hatched around 11:00pm" looks healthy" and now there is six pipping. I have kept the temp at 99 to 100,and humidity at 46 to 47,except for candling one time and filling up the water trays,opening a total of around 6 or 7 times and jumping the humidity to 72 at 2:00am the 15th. Is it normal for them to start hatching a day or so early? Was my temp off? I used four to come up with three that showed the same reading.I also used one type that shows the temp and humidity. Of course I will know for sure in a couple of days,but any thoughts would be appreciated.My first time as you can tell.Thanks.
