Hi all! I'm new here, this is my first post! I have a broody hen, sitting on 7 eggs from a neighboring farm. (I don't have a rooster) Tomorrow will be day 7, and I have a few questions! 1. I am completely new/ untrained to candling eggs, other than YouTube . Should I reasonably be able to tell if anything is happening in the eggs? They are all varying shades of brown eggs. 2. If nothing is developing, is switching out the eggs an option? Or should I not do that? Will the hen abandon the nest a week before the new eggs would hatch b/c she thinks they are duds? Or, will she stay on the nest, but it would be too long for a hen to sit since I know they lose a lot of body weight when broody. Thanks!!
