I have a little giant still air incubator. I am doing dark shelled eggs and have mostly left the eggs in the bator even if they were questionable because I was worried about tossing a good egg. I am now 2 days beyond my hatch date and today I smell a stinky smell coming from the bator. I have no pips no movement at all. The smell isn't very strong so I would have to open the bator and handle the eggs to figure out what one is bad. My questions are, should I open the bator and try to figure out what is the bad egg, and also should I be doing any float tests or anything yet? I'm only 2 days beyond the hatch but I'm thinking this isn't good that I haven't seen anything. I have had bad luck thus far so I'm going to assume my bad luck will continue and I'll probably end up with no chicks. But in the event I am wrong I don't want to do anything wrong to stop any from hatching that might. Any help would be great, im super frustrated and I don't know what to do and I'm in dire need of advice. Thank you in advance for any help I can get!!
