Dr. Quinn would have needed to put her entire arm into the cow to help with the birth.
Not quite sure how Sully heated that water on the open fire in a wooden bucket.
Sully told Dr Mike about her long brown hair when he first met her. But her hair was up and she had fallen in a mud puddle.
When the orphaned baby calf is scared to go into the fire, Dr Quinn picks him up and tells Brian to get into the wagon. He only got off his horse to help the calf. His horse was still there. Also, why didn't she just put the calf into the back of the wagon. Brian or Colleen could have stayed with the calf. Instead she carries the calf with her on the horse through the fire.
