I set eggs on June 14th. Here it is 7/9/2009 and nothing has hatched even though candling showed chicks. So I crack open a small hole at the end of the air space and see that one egg had a half formed dead chick. Then, I crack open another egg, no chick so I discarded that one also (I couldn't see through that egg). The third egg I put a little hole in the air space so I could see what was going on and it does have a live chick in there however it doesn't seem to want to hatch yet. Also it seems too small for the number of days it has been in the incubator which is weird. What should I do now? Wait another week?
