I know there is a ton of questions been asked about this subject.. i built a homemade bator from a mini fridge. it will hold three turners but i only have one in it now and its full of quail eggs.. its holding temp really good ranging from 99.3 to 99.9 . my question is how do i get the humidity up .. i have the heat source at the top and i put a water pan at the bottom and the best i can get it to is about 40% so i added a sponge with little to no results then i added a small bowl of water with a sponge to the top shelf in front of the heat and it did come up to about 48% which is good until lockdown.. i have four vent holes in the sides two are at the top of the sides at the back and two are at the front on the bottom.the two on the side at the top are bringing air in and the two at the bottom on the sides are letting ait out. i also have small holes 1/4 inch five of them in the back behind the fan so it can suck in some fresh air from there also i have adjusted the vents every way to try and get it to rise but dont seem to have any luck.. could someone tell me what i can do or if i need more vents or just what.. i thought about putting another heat source at the bottom to get the bottom water tray warmer so maybe it would put out more .. any help or ideas would be greatly appreciated.. thanks
