I finally have my Ameraucana and Marans eggs, but I can't get my bator to work right now!! I have a little giant that has a fan in it and an egg turner (that is fianlly working right) I can get the temp steady at 100% but I can't get the humidity right! What are the exact numbers that I need and what is an ok buffer to go up or down out of the right temps?? Ex: If the right temp is 99.5 degrees is it ok to be at 100? and if the humidity for the first 18 days is supposed to be 40% is it ok to be at 45%?? Please help I want to get my eggs in but I am scared to ruin them!!
