    That drop in temps could be either bad battery on thermometer or the cause of some of your humidity issues.

    But you did say its not as bad now, so a fan added in with a low 20-40CFM rating could help move air around and stop build ups

    Re: Humidity in egg tubs: how much is okay?
    I may be wrong but I remember a science class about dew points and altitude. The higher the altitude the higher the air pressure and this means that your dew point is much lower that mine here in florida for example. Its all a bit over my head but just a suggestion. See if this makes sense to you. At a given temperature but independent of barometric pressure, the dew point is a consequence of the absolute humidity, the mass of water per unit volume of air. If the temperature rises without changing the absolute humidity, the dew point will rise and the relative humidity will lower accordingly. Reducing the absolute humidity will bring the dew point back down to its initial value. In the same way, increasing the absolute humidity after a temperature drop brings the dew point back down to its initial level. For this reason, the same relative humidity on a day when it's 80°F, and on a day when it's 100°F will imply that a higher fraction of the air on the hotter day consists of water vapor than on the cooler day, i.e., the dew point is higher.

    At a given barometric pressure but independent of temperature, the dew point indicates the mole fraction of water vapor in the air, or, put differently, determines the specific humidity of the air. If the pressure rises without changing this mole fraction, the dew point will rise accordingly; Reducing the mole fraction, i.e., making the air less humid, would bring the dew point back down to its initial value. In the same way, increasing the mole fraction after a pressure drop brings the relative humidity back up to its initial level. Considering New York (33 ft elevation) and Denver (5,130 ft elevation), for example, this means that if the dew point and temperature in both cities are the same, then the mass of water vapor per cubic meter of air will be the same, but the mole fraction of water vapor in the air will be greater in Denver.

    Condensation happens when the temps inside the eggbox are different than the temps outside the eggbox. Just like you car in the morning because temps have dropped outside faster than inside the car. I usually run my incubator for many days with tubs inside before I ever get eggs so all the temps are balanced out and never have condensation problems.

    yeah we had a bit of a hard time with the incubator. our whole building envelope for our apartment was under construction, which involved drywall sanding, painting, moving furniture (a MILLION freakin' times!), etc.

    we had to seal off the snake area and cover everything up to prevent drywall dust from harming them. i also moved all of the reptile related stuff into the spare bathroom and sealed it off, so the bator didn't get a chance to run and stabilize. i knew these eggs were going to be laid, but it's been a complete madhouse around here.

    the WEIRD part about this season is that our first BP clutch was laid 85 days after ovulation (2 good looking eggs, one questionable egg; it was a half-boob egg, and 2 slugs. one molded and died early on, i threw it out without opening it, and 2 DIE's), and this current clutch was laid 76 days after ovulation. 5 good eggs. WHAT GIVES!?

    we're on the hunt for an old broken down wine fridge w/ glass door since next year should be a big breeding season for us. hopefully that will solve some of our condensation woes.

    what i don't understand is WHY are the temps so different between the inside of the egg box and the rest of the cooler? it's sealed off pretty tight, and it's been 8 or so days that they've been in there already.
