Premise: By the time Nat was washed and done up in a blanket by the fire , while Nursey cut his hair , a new detachment of boys arrived and were shut into the bath-room , where they made as much splashing and noise as a school of young whales at play .<br>`` Nat had better sleep here , so that if his cough troubles him in the night you can see that he takes a good draught of flax-seed tea , '' said Mrs. Bhaer , who was flying about like a distracted hen with a large brood of lively ducklings .
Hypothesis: Mrs. Bhaer is literally a hen.
