my first duck egg is starting to hatch has hole in shell about the size of a thumb nail. 3 others have pek cracks starting incubator is at 78 percent humidty and 98 degrees. I am in in Savannah Ga. so our humidty is high anyway and it has been raining for days. I have 10 baby chicks in 55 gallon rubbermaid net to the incubator. I still have llight on them even though the lowis only 70 at night and 80 to 85 during the day. They are in my garage. I have another container to set up for the ducks. I only have chicken starter but the guy at the feed and seed said that was ok to feed the ducks. How long before it hatches all the way? Do I need to any thing. other than having a nervous breakdown waiting for my first duckling? Thanks to all of you Anne. Ps. This is worst than having a baby as my baby is 27 years old.LOL
