Egg smells due today

[polishcourt]

I opened incubated yesterday to add water have home made styrofoam type incubation system and I could smell that bad egg smell I have three due to hatch Monday and one due two days ago and one due to hatch today I'm pretty sure the smell is from the one due today don't want to compromise the eggs due Monday wondering if I should discard or wait a little longer

Make sure you have the correct stinker and definitely discard. If it was viable it wouldn't stink.
A stinker is about to explode and that will surely ruin the others. The eggs need oxygen and the odiferous gasses coming off of that egg is detrimental as well.
