Hi i built a homemade incubator and have turned my eggs twice a day for the past eighteen days, the humidity and temp have been spot on at 99 and 62. However, today is the 20th day so my eggs are on "lockdown". Before i put the eggs on lockdown (Raising the humidity and stop turning them), I candled my eggs, i didn't see what all of the charts say i am supposed to see. I think its a yolk floating in the middle. Some of them it doesn't move but some of them do. The reason i am confused is that there is now bad smell and my friend (a chicken owner) says that that is what happens and they ARE still viable. Any words of advice, or words of reassurance. Also, these eggs are rhode island reds so i don't know if maybe they take longer or something?
