260 ANIMAL INTELLIGENCE 



In another case it is not distinctly taken into the 

 mouth and expelled, but is simply picked up and at 

 once dropped. 



Water is presented to the chicks. They peck at 

 some drops on the side of the tin containing the water. 



They accidentally get the beak into the water, when 

 drinking follows. 



They do not spontaneously put in the beak and drink, 

 either before this accidental result or after, and in this 

 matter they all three behave alike. 



They are seen to scratch the head with a foot. 



At this age another lot of six, which are with a 

 different mother, do drink on invitation (clucking) of 

 the mother. 



They also eat rather better on her invitation than 

 without it. 



They run to the mother from a distance of 4 feet. 



Five hours later. The mother hen drinks, whereupon 

 two of the chicks run rapidly from a distance of 6 

 inches and drink. 



One of them wipes its beak on the ground. 



The hen is later in a box, and cannot be seen by the 

 chicks, yet they move towards her, i.e. in the direction 

 of the sound she makes. 



3rd day, 2 P.M. They have been fed a couple of times 

 before to-day. 



They are now given very small pieces of meat, with 

 which they run off, peck it against the ground, and make 

 off from each other, as does a mature hen. One even 

 escapes through wire-netting into the next " run." They 

 are now out of doors in suitable " runs." 



One is seen to swallow a piece too large with no more 

 difficulty than a mature bird apparently. 



One of the chicks begins to eat lettuce, on which the 

 mother hen is feeding.
