Day 2 to day 10. I believe it is.
I wouldn't have them in the incubator but my female decided that she wasn't going to sit on them anymore.
My Peking also dumped her eggs in the nest with my mallard so I have a mix.
The nest had 13 eggs in it. 2 weeks in we candled them and left them as is. Removed the bad ones. Left 6. She was fine that night. The next night it rained hard and got cold, her nest was under water. Her & the other ducks went in their house. She never got back on the nest.
Recandled them day before yesterday, one of the peeking eggs had developed a massive blood clot and died. Went down to 5 eggs.
They all stopped laying for almost a week. Today my kids found 3. 1 mallard in the middle of the duck yard and 2 Peking in a nest instead of leaving them there they brought them in. I wasn't happy. But now they are in the incubator.
I'm going to recandle them tonight.
I'm honestly lost in all this.
