This is my very first time hatching chicks and it has been very turbulent. First a temp spike, then a power outage. But much to my surprise one pipped this afternoon (day 22). I opened the incubator a couple times to add warm washcloths because the humidity was at about 50%. But there hasn't been any progress in over 8 hours and I am really worried. Also a second egg has been rocking like crazy for 8 hours but no pip yet. Is it too soon to be worried? THANKS FOR ANY ADVICE.
