Stinky incubator?

[affacat]

One of the two pippers hatched about half an hour ago! Thats four from our batch. The other pupper hasn't hatched yet, but another egg is moving.

4 hatched... So far so good

2 more this morning. Probably going to remove the 3 in the incubator to the brooder as soon as they look dry, due to the broken shell in the incubator.

Sniff the eggs as you are taking them out and putting them back. If any have just a bit of a questionable smell get rid of them. Those eggs may be fine, some may have become contaminated. A contaminated egg can explode from the pressure building up but often they leak a white or grey stinky slimy corruption through the porous shell so look at them too. Then sniff the incubator two or three times a day until they hatch.

Thankyou very much for your detailed answer. I also had what I thought was a stinky incubator but it turned out to be 2 eggs and they had a grey watery looking patch on them. They have been discarded and now the bator no longer stinks
While I have eggs at various stages in there I move them into a second bator for lockdown/hatching
