It has 2 water holes on the side you use hole A for the first 1-18 days then after that u open up the B water hole then add water to both holes half way this will increase the humidityAt this point I'm kind of leaning in the direction of the Nurture Right, because of all the great things I've been hearing about it! Can you set the humidity? Sorry I don't know anything about incubators
Thanks!
