I have 5 new chicks that were hatched under my hen. I still have 8 eggs to go. Do I need to move the chicks into a brooder until the rest hatch or just leave everything alone? The hen is taking good care of them. I keep checking on them and she takes them out for a walk and then they all go back to the nest. The other eggs should be hatched out by the end of the week. Thanks for your help!
