I have a question for my daughter she is trying to hatch three egg in a home made incubator she got the idea off utube. It's a styrofoam ice chest with a light type set up and the directions say set a bowl of water in it for humidity but its only reading at 37. Is there something she can do to raise the humidity? She said she also has a sponge in the water.
thanks for any help.
 
Might want to try adding more sponges (not in the bowl). The humidity
Will be affected by the surface area of the water and not the depth. You need to add more water surface that is in direct contact with the air.
 
What temp is it at.temp goes up humity goes down.temp goes down humity goes up.make sure ur temp is constant and not to high and humity will be easier to control.
 
try a sham wow or micro fiber cloth soaked in water just placed in the cooler. I am having trouble getting the humidity under 70 with that method using same type of incubator
 
Actually, some people recommend the "dry hatch method" so that your eggs don't grow so fast and then the chick drowns. The humidity around 35% would do for that, but many recommend 45% if you aren't doing the dry hatch. Then up the humidity to 65% on day 19-21.
 
She said she has a micro fiber so she'll try that. And she'll try to make sure it raises on day 19.
 
Where is the light installed within the cooler?

I wound up installing the candelabra light fixture through the short side of the Styrofoam cooler about midway up. Filled a small dish (about the size of a small cupcake) w/ a cut sponge and topped it off until saturated. Once my first chick pipped, I moved the light to the corner of the cooler lid. This affords the chick an opportunity to regulate its temp preference by moving closer/further from the light source - plus I wouldn't want an jumpy chick bouncing off a hot, low-hanging bulb. I also placed a doubled-over piece of aluminum foil (about 3/4 as tall as the cooler) btwn the eggs and light source. This redirected a fair amount of light back toward the water dish and prevented the eggs from receiving too much radiant heat.

The previous poster was correct in the fact as temp goes up, relative humidity goes down - UNLESS more water is added to the environment.

For me, keeping the sponge fully saturated resulted in a RH btwn 45-54%, with a temp btwn 99-102 deg. I punched eight equidistant, pencil-sized holes in the cooler lid and capped them w/ duct tape initially. I removed the duct tape on these ports to regulate temp & RH. On the days the bulb decided to run hot (spiked at 106 a couple times), I'd crack the lid long enough to pull temps back to norm. I used a wireless thermometer, so I could monitor temps while I sat in the family room.

It all seemed to work.
