Iain Utah, I am literally sick. I could PUKE right now. I'm trying not to get too sick about this but I am.

The cooling and misting is so stressful and time consuming for me but I know it has to be done. I have been so diligent about doing it but last night I was so tired, I feel asleep. I can only hope for the best. :/
Oh dear I can guess how you're feeling but was your home so cold overnight?
Now Emdens and Chinese are tough critters and usually incubate well, even better these eggs were over the halfway stage at about Day 18. With those facts established there every reason to hope things will be ok. As Iain said those eggs over 10 days continued to develop.
For today leave well alone and miss this evening's cooling. Instead relax and get some well earned rest as it'll do you and the eggs more good!!! Just maintain stable conditions over the next 36 hours. If a quick candling tonight would reassure you they're alive then go ahead but keep it brief.
Wishing you the best of luck with this batch.
Pete
