for Uno and anyone else interested

After I got to this line I did not read any further:

Bring the humidity level in the room up to between 50%‐75%
preferably 50%.

He is not doing a dry hatch! His humidity is even higher than in my incubators. The only difference is he is humidifying the whole room and not just the incubator. The humidity in the room will be the humidity in the incubator unless you add water to your incubator.

My house is around 15- 25% humidity. Dry, dry, dry. I add water to the incubator to bring it up to 45% to hatch. My hatches are drier than his are!

Good point Sue, I think that even though he is not doing a dry hatch per say, he is saying that many people who have poor hatches do so because of drowning their chicks.

This method appears to be dry hatching but as has been pointed out, a room with ambient humidity of 50% is hardly dry! Also, I don't think I want any room in my house having a constant 50% moisture level, maybe the bathroom just after a shower, but that's it!

No, this guy is playing it down the middle, no humidity in the bator, but humidity in the room. He cannot call himself a dedicated dry hatcher if that is the case.

But the discussion of dry or wet hatching almost cannot exist outside the larger picture of ALL THE FACTORS that affect hatching. Like the author mentions, egg quality, health of birds, storing methods, different temps for forced or still air. Hatching is like baking a cake, LOTS of ingredients involved.

Thank you Coopslave, interesting read.
