Hen, in the Museum at Brussels, a creature covered with 

 feathers and hair, said to be bred between a rabbit and a 

 hen, iii. 134. 



Hen of the common sort ; moderately fed, lays above a hun- 

 dred eggs from spring to autumn, iv. 25. After three years, 

 becomes effete and barren ; clutches one brood of chickens 

 in a season ; instances of two very rare ; number of eggs of 

 a domestic hen in the year above two hundred, being well 

 fed, supplied with water, and at liberty ; trodden by the 

 cock or not, she continues to lay ; eggs 'of this kind never 

 by hatching produce living animals ; her nest made without 

 care ; clucking season artificially protracted, and entirely 

 removed, in what manner; left to herself would seldom lay 

 above twenty eggs, without attempting to hatch them ; as 

 she lays, her eggs being removed, she continues to increase 

 the number ; in the wild state seldom lays above fifteen 

 eggs; particularities of incubation ; affection and pride after 

 producing chickens ; every invading animal she boldly at- 

 tacks, the horse, the hog, or the mastiff; marching before 

 her little troop, by a variety of notes, calls her train to their 

 food, or warns them of danger ; instance of the brood run- 

 ning for security into a hedge, while the hen stood boldly 

 forth, and faced a fox that came for plunder ; artificial me- 

 thod of hatching chickens in stoves, practised at Grand 

 Cairo, or in a laboratory with graduated heat, effected with 

 woollen hens, by M. Reaumur ; by these contrivances, from 

 a hen naturally producing twelve chickens in the year, are 

 obtained artificially above two hundred, iv. 132. Common 

 hen supplies the place of the hen pheasant, when refusing 

 to hatch her eggs, and performs the task with perseverance 

 and success, 151.
