I have three eggs in the bator. Only one loos like it might hatch though. It chirped all last night, and now it has pipped and the egg is rocking back and forth. My question is...How long does it usually take after a chick pips for it to hatch? How long should I wait b4 trying to help it? The humidity is at 53% and I can't get it any higher unless I open the bator.
