I have 5 green spalding eggs going into lock down today.I am using my styro hovabator right now because I just got married and haven't gotten a chance to move my cabinet. The problem I am having is with the humidity. I can fill the trays but I am worried that the water will be gone before the 30th day. We are going out of town on Friday and won't be back until late the day of hatch. What can I do to help keep the humidity up? I thought about putting cups of bowls but dont want the birds to knock or fall into the water and drown while we are gone. I will also have a dozen golden cuckoo marans hatching the same day.
