Hi Duckman!

I love hatching ducks. I keep my humidity between 35-and 45% as much as possible the first 25 days. Then, up humidity to 75%. 90% is a bit high.

https://www.backyardchickens.com/t/491013/goose-incubation-hatching-guide-completed I think you will find this link very helpfull. I use this to the dot for goose eggs, and its pretty much what I do for ducks allready. However, I only cool the duck eggs for 15 minutes, not 30, and I spritz mine directly 2-3x a day, just like a mama duck getting up for a quick snack and swim, then back to the eggs.

Happy Hatching!

Hi! I’m trying to hatch duck eggs some four now too. My pets ducks tragically got taken by a predator and my girl left eggs that I’m
Praying I can get a duckling from. Any advice would be so helpful. Mine range from almost a month old to only a few days ago. I read somewhere on here that a woman incubates eggs even if they’re a month old and has had success. I got an automatic rotating incubator I’m on the hunt currently for a thermometer with a humitity gauge. I didn’t know anything about spritzing the eggs, does that help?

I have a Janoel 10,I have 2 temp/humidity gauges, Im keeping my temp at 99.5 and humidity between 20-25% I had it higher I started at 50-60% and started lowering it on day 5 and the air sacs still looked too small, so I kept lowering it every day Im not adding any water and I'm staying between 20-25%. Everything I read it sounds like thats WAY to low but my air sacs look about where they should be now the ducklings look good lots of movement and veins so any suggestions? Should I not worry about the humidity gauge and just go by the air sac size? I'll post pix

I’m trying my first hatch as soon as my incubator gets here. My two pet duck were tragically killed this weekend and I’m desperate to hatch at least one of their eggs. What do I look for when I candle the eggs? What does the air sac look like?

A month old is pretty old plus they would need to be turned at least once a day to avoid sticking to the side of the shell. I have never been able to get development with an egg that old. Usually after 2 weeks you start loosing fertility. If we could keep eggs for a month that would be awesome for a lot of sellers. Lol I lost a female recently and I have some of her eggs in my bator so far out of 7 eggs three of them got tossed they were early quitters. When u see development and it’s usually on day four or five you will know what your seeing. It’s very obvious. I call it the spider because it’s exactly what it looks like. A spider with all these legs. Reality is the embryo growing and developing veins.

I agree, a couple weeks old is about maximum, but set whatever you have room for. The oldest ones may not start developing, but if you have room in your incubator, it's worth a shot.

This is what you should see when candling, this one is about day 7 or so.

Good luck!

For several years I've hatched chicken eggs and next spring I intend to hatch both chicken and duck eggs at the same time. I've talked to several people and read the literature and "how to" book that came along with the incubator. It looks like the temperature is the same and humidity is similar. Since duck eggs take a week longer, they will go in a week sooner. After a week I will add the chicken eggs and 18 days later I should be able to do lockdown and proceed as I usually do. Hopefully I will get both peeps and ducklings.

I know this is an old post. But I have some chicken eggs on the way and duck eggs I just set. How did your chicken/duck hatch in the same incubator? What humidity did you use for setting and lockdown? Thank u!
