Hi. For about 4 years we have bought day old chicks and broods them. This year we did straight run and raised the cockerels to 6 months. Two weeks ago they were processed for meat. Today we discovered one of our pullets leading around 10 chicks! We have never had a hen hatch chicks. We are in northern IL and it is supposed to freeze tonight. Should we put the mama and babies in a pen in the barm by themselves or leave them with the flock? She didn't brood them in the coop but has led them back to the vicinity of the coop. We have about 30 hens. Thanks for your thoughts.
