Excellent Good Luck. I never want to tell people how to do things, but what you were describing did not sound good! I hope your hatch goes great. I hope you will think to update this thread at that time! :)
There is a chance they might hatch, but there is also a risk of bacteria getting into the eggs and killing any chicks. It isn't a good sign that they stink after you washed them. I don't want to decide for you, but I am wondering if you could get some new eggs from someone else? Or day old...
At least one of them isn't good, or another bad egg might have broken and gotten on all of theml. It is up to you, but good hatching eggs should not stink. Sorry,
