I have my incubator locked in the linen closet so the kids can't mess with it and it is draft free. I hatched out poults last week and when the hatch was over I cleaned the incubator out with oxine and let it sit out in the sun for the day. I set this hatch of chicken eggs(51) Friday night and the past few days I have noticed when I open the closet door I smell a nasty smell and when I get closer to the incubator I smell it worse. I think I may have a bad egg or two but how can I tell? I don't see any eggs seeping or cracks but I am afraid I am going to have one explode or the "bad" one contaminate my whole incubator and kill off the good ones. I will add oxine to the water today.
