My chicken egg hasn't moved, it's pipping stage and i see his beak but he hasn't moved, i think that he started to pip at late at night on day 17, i wasn't ready for him yet so i had the humidity at 55% and has never moved from 37.8 celsius, i am using the janeol 48 egg fully automatic egg turner. When i relize that he had pipped i increase to humity to 70-75 % humidity and at 37.8celsiuss, tried to increase humidity more but couldn't store any more water in also used to 2 spondge's. 6 hr's after i notice that the pip hadn't changed, so i had a good look and heared no peeping, wasn't moving, touched it beak and still did move or peep, the membrane is pure white and doesn't look to be dry out, haven't touch the egg since then. My other 9 chick's sould be pipping very soon. Can you please give me some reason's why this has happen and how i can fix this for my other chick's.
