Hi everyone! I just bought my first incubator. I purchased the Farm Innovators, model 2150. I have never incubated any eggs, this will be our first experience. I decided to make this purchase to expand my flock. I have one question but am really interested in feedback from personal experience or tips you all could provide to a beginner. I know I will learn from my own mistakes and as I go but I honestly have no knowledge at all about doing this and would really like for my first time to be a success. There seems to be a lot of info on temperature/humidity but not slot in the eggs aspect. Do you start with a one day old egg or I have some eggs over a week old. Should I use the older ones or should I only use a newly laid egg? Do you all check to make sure the egg is fertile or take a chance either way. Any feedback and tips will be greatly appreciated. Thanks!!
