I set 34 Australorp eggs 23 days ago. Twenty-nine hatched between mid-day on Day 21 and the end of Day 22, and they are sooooooooo cute! It's now Day 23 and I have 5 eggs left in the incubator unhatched. One had a tiny pip hole that went nowhere.... I assume that one has died and the other 4 have no sign of any pipping. I've put all of them up to my ear and hear nothing. When do I "pull the plug" on those last 5? I know I should then take a look to see when things went wrong (if indeed they were all fertilized... my first time round and candling may not have been accurate), though I am NOT looking forward to that.
