We built a homemade bator to use as our hatcher since we have two clutches going right now. One due around the 4th and one the 11th. So we have the temp and water trays going. What I was having a problem with is the accurite says 55% so I need it a little higher yet, but the glass pane in the top has water beads all over it. Does this mean we need to add a vent port up on top to relieve the water build up yet more water trays in the base? We haven't added sponges or anything yet either.
