Unabsorbed yolk sac

[IncubatorNoob]

Hello, I am new to incubating & hatching eggs. I had this duck egg in with my turkey eggs. The temp was set on 100, humidity for first 25 days was between 55-65%. During lockdown the temp was still 100, and humidity was between 65-75%. I had 5 turkey eggs and this duck egg. 4 out of 5 turkey eggs hatched (5th didn’t take). So all that was left was this duck egg. Well day 29 (almost day 30), and still not pip or hatch. So, I (being new to this) to it upon myself to investigate. I cracked it opened and this is what I was given. I tried looking up any info on this, and google is useless. Did I do something wrong, was it still in the process of potentially hatching, or was it deceased before I opened it up? Any help is greatly appreciated!

That's higher that what do. If you do it again, I suggest getting an additional sensor.

Whatever you get, make sure you check the accuracy by doing the salt test.

What type of duck? Any chance it was a Muscovy?

Was it alive when you opened it?

One website I read said 45-55% humidity, but most said 55-65%. So I went with that one. It was not a Muscovy duck. It was white ducks (I call them Aflac ducks), but also had a tan with brownish green head. I don’t know the name of them. No it wasn’t alive or noticeable heartbeat when I opened it.

I think you'll find that most people here use a much lower humidity setting, but if your eggs lost enough weight and the air cells looked like the picture below, stick with what works.

Sometimes they just quit, and we never know why.

My turkey eggs did great! But this poor duck, didn’t stand a chance it doesn’t seem. I bought a new plastic incubator with the water bottles on the outside, and it did great. Prior to this was one of them old styrofoam ones, and NONE of my eggs hatched, I had around 12/13 eggs in that one. The reason I’m brining this up, is because I cracked 2 of them open in the old incubator and they were the same as this duck egg (they were turkeys, not ducks). I’m more into incubating turkeys than I am ducks. Just a Quick Look, what humidity do you suggest for turkeys (for the first 21 days and during lockdown), also too what do you recommend for humidity on duck eggs. Any tips or tricks for more successful hatchings, would be greatly appreciated! I want to get more involved in incubating!
