Hello all,
I had a question about dry incubation. I am in thr uk and have thoight about dry incubating, i have incubated twice previously at 40-50 percent humidty and have not had mixh luck and the chicks that did hatch, came out really wet and took along time to dry, were they looked like someone had given them a shower.

My question is what humidoty is acceptable for dry incubation, i jave been running the imcubator for a week now and my humidity has averaged 26 percent, chicks are forming well in growimg in the eggs, but is this a acceotable humidoty level for hatching. I have seen people saying they dnt add water till it goes to 15,but what value should you aim to average the humidity at for dry incubation?
 
I like 30 percent and your right on track with that. It's humid in the UK and can see where you wouldn't have to add water until the hatch. I bump mine to 70% prior to hatch. Candle around day 15 to see how the the air cells are growing. If of the right size then then up humidity if they could stand to grow more wait.

The entire 18 day to up humidity is not a rule or anything. It's a general guide and works well as many have auto turners they are taking out of incubator that day too. I've waited as long as morning of day 20 to give the air cells as much time to grow as they can. That's when we have wet springs and the incubation is running closer to 40%.

Thank you, just to clarify, would you say 26 average for the first 18 days is fine?
 
As long as the air cells do not look too big for the amount of days of incubation. There are many charts on line to look at in reference to what size they should be.

26% should be fine but if your worried then try to get up to at least 30-35% by adding a few drops of water. Check the air cells at day 7, 14 and 18. Too big, add humidity, too small, drop humidity.

Thank you for the information, i will keep a eye out on the air cells and adjust accordingly
 
I have checked the aircells today and have attached pictures of the aircells and marked them, theyve been in the incubator for about i set them on 14th of june sk roughlty11 days now, would you say they look right.

Also not sure if this is a stupid question, but should you have the room window open where the incubator is placed?

They look good to me. I wouldn't leave a window open as the temperature outside of the incubator affects the temperature inside it, and fluctuating temperatures from the window being left open could change the temperature inside the incubator. A stable room temperature is best. There's more than enough fresh air inside your home for your eggs.

I've read not to let the humidity fall below 25%. I live in a humid environment (it's regularly around 70% indoors) yet I still have to add a little water (2 full shot glasses) to keep the humidity around 30% in my incubator. So it all depends on your set-up and environment.
