Hi everyone! First off sorry for all the posts. I lost my first load of eggs so I'm desperate to get it right this time! So 6 out of my 7 eggs have piped externally. However, it's not large holes or anything. It's just a slight crack in outer shell. (See pictures attached) The first one piped almost 24 hours ago and has been verbal but has not made much progress. The others piped roughly 12 hours ago and again, not much happening. I'm just worried that they will not have cracked the egg enough to continue breathing for much longer. I'd be greatful for advice.
