hi ..the 3rd egg is definatly fertile or was ..in the two good eggs i can clearly see the blood pumping through the vains and the chicken starting to evolve..but the 3rd egg is not as clear to see through .but it has grown...i can see big vains, but i see no pumping,i suppose ill have to wait and see,,the thing is ive got a new automatic incubater ,it only holds 3 eggs..ad if it does explode it will make a rigt mess..these incubators are not designed for an exploding egg.i think it would brake it..and they aint cheap..ill check them again in a few days and see if has grown any more,,,,,,{question} can a bad egg still grow ????
