Yes, me too. I run 75% at "lockdown" and once my first chick hatches I am at 85%. But it has been working good for me. My last several hatches have been great. The only thing is, like you also said, it takes the chicks a long time to dry. Once I was hatching in the mini and it was very full. The octagon 20 was empty. So I turned it on, no water and as the chicks hatched I moved them right to the 20. That batch of chicks were literally the fluffiest chicks I have ever seen in my life! Lol.
Yes, I've had great luck with loose air cells. But these are totally detached. But I really would love them to hatch. Ugh. It's so sad what shipping does to eggs. Like you said, I still set them. I'll still try even though I know the odds.
Can you still see blood vessels? Does the chick move around when you gently turn the egg? Like it swishes around? It might just be the picture and I'm hoping it is...but it looks like it might have quit. Check for the veining. If it still has good veins then it's probably ok. But if it looks like veins are receeded or there are no more veins, then it would be dead.
Make sure you calibrate it yourself even if it's brand new.
X2! I take advantage of the high humidity to open and take out shells, candle unpipped eggs and turn over pipped eggs. If there is condensation I take a paper towel and wipe it off before closing it up again. When I first got my octagon 20 and I was struggling to keep humidity at 60-65%, I hated it!! I felt I couldn't open the incubator and I really needed too, as 1 egg was having issues. Ended up boiling pots of water in the kitchen to up ambient humidity. It was a pain! Much prefer it high, so I can open needed.
Again, for me I will NEVER risk loosing babies and I can tell you 80% did kill them, why because when I first started out I read all over the internet, humidity should be this temp this, blah blah blah and one factor it stated 80% humidity, welll what I didn't read is this was for WET bulb not what i was using. It was HORRIBLE to see 10 babies make it all the way to lockdown and then each one booom boom boom died off. it was horrible.
I think the best thing for deattched don't even shift them. Just let them sit there completely still, I have read some people have had success but guess what. When I asked them ok tell me exactly what you did, There responses STOP, this tells me, they are fibbing. Yeh alll of a suddenly then can't tell me exactly what they did to help deattached air cells. KIND FUN FUNNY HUH? I have will have to experienment, I wonder if you put a tiny PIN hole at the top of the shell and leave that egg there for a couple of days if that will help get those Deattached air cells to STICK. HUMMMMM...
I LOVE EXPERIMENTING with things..
