I need some help

[aquafuzz]

I hope someone can help me. I have been incubating some wild duck eggs now since the night of May 15th. They are in an incubator w/ turner, temp around 99.5-100.5 and humidity 65-75%. We candled them last night and the air sack has grown and is large and off center. In past candlings we have seen the progression of the chick. Started with 8 had one yoker and now one that did not form all the way so down to 6 good ones I'm hoping.

The problem comes in that I'm not sure of the time line of when they were laid, and how long to keep them in the turner. I don’t want to keep them in the turner any longer than they need but I don’t want to pull them early. In other words just not sure when to stop turning?

Please help.......

Did you candle them when you started?

If there was nothing there at the start, you turn to day 26-27...

If you think they were a week along then you stop turning at day 21-22.

They usually require a full 30 days.

I'm wondering if your humidity is too high even though I know duck eggs require more from start to finish.

There was an embrio starting...so i think I got them about a week along. Some of the websites that talk about duck eggs call for the humidity around 86% during incubation then up to 94% during hatching...its all I can do to keep it at 70%. They also say to stop turning around day 26-28, thats my issuse. How far off my days can I bee and not harm the chicks by not turning or turning if I miss the stop turning dates?
