I have 14 beautiful, growing so fast my head is spinning, chicks. I am a New Chick Mommy with my first click of chicks. They are a flock of mixed breeds. One chick is digging what looked in initially like a nest and is "pine shaving" bathing area. I am very hands on with them and none of them have any bugs or skin issues. What am I missing? Or is this normal? I have expanded their brooder (6' x 3' x 26"), into a multi-level brooder (6' x 3' x 5') with roosts, so they can stretch their wings until their new coop is completed. Maybe I could add another level with a sand box dust bath and swing set?? I tried to get a photo of her in action, but of course she wouldn't comply.
