Do you have the vent holes open? If so try to cover 1 or both of them with tape and see if that helps. Is it a still air or do you have a fan? Also keep in mind that this cooler weather pushes the humidity lower and that could be part of your problem especially if you run the heat in the house. You could put a towel going around the sides and keep it wet and that should help.I have a question for everybody who hatches ducks in an incubator... I have my temp locked in at 99.5, the problem I'm having is with the humidity. I am using a little giant 9200, I have filled up all the indention's for water filled and it brought me to 50%, I added a large sponge and brought it up to 60%... I need to get it up to 85%... Any ideas on how to raise it?
