my second round of chicks was supposed to start hatching today. this hatch has been fraught with problems, mostly because my Orp hens seem to be a little hatching stupid, so i wasn't surprised with nothing happened today. i'm not rushing to any conclusions and just giving them an extra couple of days. anyway, i went in tonight to see if anything was happening and i could SWEAR i heard chirping. i have older chicks nearby, but the broody and these eggs are in a room made of cement block and i seriously doubt i would be hearing 5 3-week old chicks through all that cement. but there are no pips... so, is it possible to hear them chirping IN the egg? does that mean i should be hopeful?
