I am a fairly new chicken owner. One of my black australorp hens went broody about 4-5 days. She is sitting on about 5 eggs. We do have a rooster so not sure if the eggs are fertile or not...So my question is if she does end up hatching her chicks out, should I leave them in with my 13 other chickens or put them into a separate pen. I don't want them getting hurt. I basically need guidance as to how to go about this. Thank you in advance!!
