So my bobwhite quail starting piping on Sunday, well at least one did out of 23 and then more and more starting piping yesterday. But I am kind of concerned about them because I haven't seen any progress in their hatch. Should I be worried about them? I am used to baby chickens piping and then hatching in less than 12 hours after but I am just making sure. How long is it usually to when they pip to when they start to hatch?
