LEG WEAKNESS. 



^Vg" EG weakness is a term which is popularly 

 II used to designate any condition in which 

 /^^r birds find it difficult or impossible to sup- 

 port themselves upon their legs. It may 

 develop in young chickens kept in brooders in which 

 the heat is not properly distributed or where there is 

 too much bottom heat, also in those which are kept 

 constantly upon wooden floors. It is often seen in 

 heavy cockerels, and also occurs in flocks which have 

 been forced or which are kept in badly ventilated and 

 damp houses. 



This trouble is i)robably in most cases of a rheu- 

 matic nature, affecting the muscles, tendons and 

 joints. Frequently it consists only of bruises of the 

 feet; while, sometimes, its nature is obscure and 

 difficult to understand. 



Symptoms. — The disease may come on gradually 

 or suddenly. In the former case, there is first seen
