Hi Y'all,. I'm new to this forum, well, have been lurking for a while now and finally decided to post. I have a new little giant forced air fan and auto turner, my eggs are at day 13 now and the air cell looks fine in the eggs, but can't seem to get the humidity up around 50%, it goes down to 28-40% but the trays are full of water, plus I have a sponge in there. Any suggestions? I couldn't find a wet bulb thermometer anywhere, so am using a digital humidity thermometer. Thank you in advance.
Assuming that your hygrometer is correct and you have both plugs in place in the incubator, I would suggest a humidifier in the incubator room. If your house is too dry you will never boost humidity without a real fight. Nothing wrong with 40% humidity normally. If the air cell is the right size for this far along then all is well no matter what your readings on the hygrometer.
I have a LG still air and it is really hard to get the humidity up! I have filled all of the tray!! I dont want to use a sponge because I want to save that for hatching....but then...uhhhh
As Kstaven says, nothing wrong with 40% at this stage and you do want to raise it between 60 and 70% the last 3 days...I'm into the second week of a hatch myself and finding with this cold weather keeping the humidity between 40 to 50% harder so I added a small humidifer (a small childrens steam vaporizer can be used too) this week to the kitchen where I keep my bator.... I also add a sponge the last 3 days into the hatch too...
Thank you for the suggestions. I added a steam humidifier so should see a difference soon. Thank you.
at the end i took the turner out of the LG and i put a bowl full of wet paper towels in the middle of the bator during the hatch. every day i pry one of the plastic windows up and carefully add more water to the towels to keep them soaking. don't know if this is a "recommended" idea but i've had four babies hatch out okay so far. also, it's a still, not a forced air so there's that variable too. good luck!
