My 1 year old black star hen went broody on May 15th her eggs are due to hatch June 4th or 5th. I am not sure that all her eggs if any were fertile. This is new for us never had a hen go broody we have one roo and 12 hens. She has been sitting on 6 eggs and is a really good mama. We just left her in the nest box she picked, supplied her with food/water, let her out twice a day till she was ready to re-enter the nest and made sure the other hens could not get in with her. Love her Darth Vader entrance back to the nest. My question is if the eggs were not fertile (nothing hatches) how will this affect my hen? Does she know when the time is for them to hatch? What do we do for her? Please advice the chicken journey is always new and educational here.
