    Am I right in thinking the humidity rises on it own during the hatch ? I don't have to add water right before the last 3 days ? I am new to all of this.

    I live in the humid South and that is the reason I don't add water until the last three days. If I lived in an arid region, I'm sure I would have to keep water in the bator.

    I weigh the eggs looking for them to lose about 4% weight the first week, 6% the first half of the incubation period and looking for at least a 12% loss of water weight. I pay attention to the air sac size & adjust accordingly.

    Quote:Humidity will or should rise during a hatch once the chicks have started pipping and zipping out of the shells. But you need a good range level before that starts happening.

    Humidity ranges that I use at my house. Day 1 thru 18: 40 to 50% range.

    Day 19 thru 21: 60 to 70% range.
