Turkey hatching what did I do wrong?

[cedar post]

Ok I started four turkey eggs for my dad. 7 days later added blrw eggs with them. Did the lockdown four days ago. The chicks started hatching 2 days ago as well as 2 of the turkeys. one turkey was out today and I could see the other was not moving so I went in and that one was dead with beak sticking out. I seen another turkey had a hole started and that one was also dead. The last one was fertile and died when it was absorbing the egg sack. Could I have drowned them at hatch. I had 30 chicken eggs in with them and ended up with 27 chicks and one lonely turkey. I must have done something wrong, first time with turkeys.
Any help would be great I was going to try start a bigger batch of turkey eggs later this week but need to figure out what went wrong at hatch on these. The humidity was running around 72-76 percent after lockdown and temp was 99.0- 99.8 during the hatch time. Maybe it's harder to do turkeys I need to know. Thanks Mike

From what I have read on the turkey forum turkey eggs only hatch well when they have been at 60% humidity or higher for the entirety of incubation. I have no personal experience but was discussed here https://www.backyardchickens.com/forum/viewtopic.php?id=323226 by people who know what they are talking about. I'm sorry for the losses.

That's good to know I use a 1588 hovabator they are blue palm that I'm trying to hatch. I kept it at 35 the first 25 days and 60-70 the last 3 days.

Hi, I have been hatching turkeys for about 10 years now and found that the best thing to do is keep your humidity at about 50% to 55% all the way through. It sounds like to me that the little guys drowned before making it all the way out.
I have found that turkey eggs are pretty hardy. I made what i would call some major mistakes when I first started hatching them and still had 80% hatch rates when I was sure that I would lose the complete batch.
