Just curious... Me and my wife placed 20 eggs in an incubator 4 weeks ago. On day 20 the eggs started hatching. All of the Australorp Wyandotte crosses hatched on day 20,21,and a couple on day 22 but the 4 bantam eggs did not. I candled them and 2 were not viable so I removed them both yolk no growth. The other 2 were still moving. Finally today (1 week later) the 2 bantam eggs hatched. Does anyone know what would cause them to be so late. Just a side note today was going to be my last day If they didn't pop out when they did, I was planning on removing them this evening and reloading.
