Well I put some wax over the hole but I think I may take your advice and discard it anyhow. I don't want to take the chance if it can harm all the other eggs.
I Just got my eggs from miss prissy and I noticed on one egg that there was a tiny chip in the shell but the membrane is just fine...is this egg ok to hatch or should I discard it? Is there anything I can put on it to make it safe for the growing chick?
