Quick backstory... I think we may have a roo pretending to be a hen, four eggs last week looked fertilized. 2 out of my 5 girls are laying. Onto the questions... My RIR has gone broody one week after laying her first egg. She and one of my BO's share the same nest box, and she is currently sitting on their 9 eggs. I want to let her sit on them to see what happens. What will happen if none of the eggs are fertilized? If there isn't a roo, and hence no need to sit on the eggs, how do I break the broodiness? She comes out of the coop in the morning to eat and get water and occasionally throughout the day but I regularly find her in the nest on her eggs. Also, I noticed this morning that she is pulling feathers from 2 of my other hens. How do I stop this behavior?
