My rouen duck eggs have been in the incubator now for 30 days today. I am not sure what to think, they were supposed to hatch at 28 days I thought. I am new to this, I have never hatched eggs. Any thoughts or suggestions?
 
Could you give us some information on temperatures, humidity, results from candling, and if you weighed them, the change in weight?

MInd you, I am asking because I have read about these things on the forum - I am not a hatcher.
 
The temperature has been running 97 - 99 degrees, Humidity was bumped up in the last 3 days to 75 - 85 or so. I candled them last Friday, May 17th, two had movement, 1 was questionable. I gently moved them off of a tray to the wire mesh. I have not turned to moved them since. I did just candle them with a flashlight but didn't move them. I didn't see any movement, 2 had a good size air pocket, 1 had a little yellow fluid ring just under the air pocket. Some veins are still visible and are red in color. I just do not know what to think as this is my first time hatching any birds. Any advise is welcome. Thank you.
 
From what I read, your humidity is too high. Let me check and find the reference.

Here is a quote from another thread https://www.backyardchickens.com/t/861428/no-hatching-progress-24-hours-temperature-problem

I have been incubating 5 duck eggs for the past 28 days (today is day 29). Yesterday, 2 of the ducks pipped, but neither one has made any progress in the last 24 hours. I've read on numerous posts that duck eggs can take a long time, but I'm wondering if the temperature in my incubator is too low. The thermometer reads between 93 (light kicks on) and 99 (light kicks off) degrees, with the humidity reading between 75 and 95%.

Here's my dilemma. I can adjust the light to come on and raise the temperature; however, I would have to remove all of the eggs to do so. The wire floor that they are sitting on is above the temperature gauge. So my question is, after 24 hours, should I leave them alone and give them more time, or should I remove them (I do have a heat lamp I could place them under while I adjust the temperature) and turn up the heat? And if the answer is to leave them, at any point should I adjust the temperature...say if nothing has happened for 36 hours, 48 hours?

Thanks in advance. Like all newbies, I'm getting nervous!!!
Here is the answer from Lacrystol ( bolded part of it):
At 95% they will NOT survive, ducks can NOT tolerate humidity past 80%, I have read a lot of internet post saying they need 80 to 90% humidity I can tell you this is WRONG information. TOTALLY wrong, how do I know when I first started I kept mine at 80% and guess what my results were, DEAD. all of them died. 65 - 70 is Good but 70 is still pushing..

You need to Immediately make them a safe Hole and LOWER that humidity, they will need to dry up some, I'm sure they are all very very sticking inside causing them to struggle trying to get out of that shell. they will give up before they get out. If they haven't already, you really need to get that Humidity DOWN... get it down to about 45% so some of that water can escape out of there..
