Today is day 21 for my chicks in the bator. I had one that had peeped by the time I got home yesterday around 6 pm and it was unzipping at 10 and this morning at 7 is was out and drying off. I have 7 other eggs in the bator that have not broken through the egg. I have a hard time hearing if they are peeping internally. Should I leave the lone one in there until someone else hatches or take it out and move to the brooder? Also how long do I wait to candle or intervene with the other eggs? I have a stable humidity of around 65% (was between 30-40 for first 18 days) and a good temp at 99.5-100. This is only my second hatch and my first I had humidity issues and several chicks were fully developed but did not hatch so I am getting worried. I have read that you can chip away at the top of the egg to see if the chick is alive, how long do I wait before this? (or should I just let nature take its course? Thanks!
