I started my incubator yesterday at about 11:30 am & kept an eye on it for 24 hours, to make sure the temp & humidity stayed consistent. I put my fertilized eggs in to the incubator at about 11:35 today. Everything was going great! The temp & humidity was staying consistent.... Until about an hour ago. Now the temp has dropped dramatically! And the humidity has gone from 45-50% to about 80%!!! My incubator was given to me from a friend & I don't have any instructions, so I don't know what the increase/decrease thing is for on the top. I have googled the type of incubator I have, but have gotten no answers as to what it's for OR how to drop the humidity & raise the temp!!!
