So I got this Brower 845 incubator from a yard sale. The woman said it works, and I am inclined to believe her as I have dealt with her on a number of occasions. So anyone able to tell me how to use it? I have never used an incubator before, and I will be buying a brand new one, but I thought I would give this one a shot first. My husband checked it over and said that all the components are working, so how do I use it? Thanks for all advice.
