So have 11 chicks and 9 ducklings so far. It is day 22 for chicken eggs and 29 for duck. Well 1 bantam egg is still alive, no external pip, think internally pipped today and still has veins.
1 duck egg, long story very short, I thought was DIS. Started eggtopsy got top piece off of egg and it moved.... No internal pip at that time. It is in the incubator and hoping to save it, top of shell is back on since it was in 1 piece. It has since internally pipped so guess I see how it goes but not very hopeful.
