I searched for answers on this and after hours of reading still couldn't find it so I apologize if it's been asked before. I have a hen that just went broody yesterday afternoon/evening. I was with them about 2:30 or so and she wasn't on eggs but then last night at 10 she was sitting. She is already sitting on fertilized eggs since there is a rooster in the bunch. Can I add a few more fertile eggs to her clutch today and will they hatch with everybody else or will they most likely not make it because of the timing?
