Ok....I am going to but my first batch of eggs in the incubator this weekend. My Buff Orps have laid almost 2 dozen eggs in the last 3 days! I understand that the eggs will need to be "candled" during the incubation process. Can someone let me know: 1. How often? 2. Is there some reference site that will show me what they should and shouldnt look like? 3. Anyone have recommendations for what I should use to candle these eggs? They are a medium brown color. Hoping to have some success on this first try. Thanks for any help you can provide!!
