DISEASES AFFECTING VARIOUS ORGANS. 71 



Causes: It is quite frequently caused by feeding too 

 highly concentrated food and too much of it. In young 

 ducklings or goslings it may be due to an error in feed- 

 ing, or to allowing them to get into cold water when 

 quite young. 



In brooder chicks it can sometimes be attributed to 

 keeping the brooder quite warm, then allowing the 

 chicks to run out on the cold, damp ground or floor. 



Treatment: The cause must be first sought, and 

 removed, if possible. If it is due to feeding too highly 

 concentrated food change the diet and feed less; plenty 

 of green food and some beef scraps should be fed. 



If it is due to allowing water fowls to get into cold 



water, remove this cause; if due to over-heating the 



brooder, or to chicks becoming chilled, this must be 

 remedied. 



For medicinal treatment, add ten drops of tincture 



belladonna and ten grains of salicylate of soda to two 



ounces of water and give each chick one-half teaspoon- 



ful three times a day, and keep them in a warm, dry, 



comfortable place. 



RICKETS IN YOUNG CHICKS. 



Rickets is a constitutional disease, usually associated 

 with derangement of digestion, nutrition dnd assimila- 

 tion. It is not as frequently met with in young chicks 

 as in other animals; however, it is occasionally seen. 



It is really a deficiency of earthy material in the bony 

 tissue.
