My Cayugas are starting to join us here in this world. I have one that started pipping this morning and one that is just starting. My wife handles the hatching of all of our birds but can't log on right now and asked me to get help from y'all. Question 1: What can she do to raise the humidity? She can't get it over 75% even though the pan is full and a wet sponge has been added and an additional small pan of water is in there and she has been misting. Hova-bator 1602 is what she has them in right now. Question 2: How long before she should intervene in the hatching process and help them clear the egg? She has hatched out lots of chicks but this is our first duck hatch. Thanks.
