Ok so my eggs were due on the 28th but 2 of them hatched on the 27th and the last 3 hatched on the 28th. I waited until tonight but none of the other eggs have even pipped and the incubator is starting to smell. I can't tell which eggs are smelling. Should I attempt to break open the remaining eggs? How should I start breaking them safely incase there are chicks alive inside? Please help any advice is great!
