Abandoned eggs, still alive? please help

[earlybirdy5]

I opened an egg today because I have an abandoned clutch of ten and according the chick that hatched with this group under a broody these eggs are around 30 days.So when I opened the egg the poor little chick was full of feathers with a veiny yolk and some yellowish fluid and it did not smell weird or anything, it seemed to around day 17 development. Did I kill it? and should I keep going with the others?

Side note...I have had this clutch in a makeshift incubator since last Friday, touchy temp for a bit but now pretty stable at 99.4-100.1 and humidity at 68-70%

I guess I should have also stated that I candled them last week and they were veiny with a decent air sac. I candled them today and they are mostly dark still with a good sized air sac. I am really lost in what I am doing at this point. Trying to save these eggs if I can. I buried the little fella that I opened, taking a picture seemed very morbid to me although maybe someone could have helped me more if they had seen.

I would leave them alone for now. If they are going to hatch they should fairly soon. I wouldn't mess with anything at the moment. It's possible they aren't alive anymore, it's possible they are. I'd just observe for now.

Thank you for responding, I have convinced my husband to do just that (give it a little longer)
