grains usually contain a higher percentage of 
protein than the other grains. By this is meant 
that feeds like bran, oilmeal, etc., are quite a 
bit higher in protein than are grains like corn, 
wheat, barley, etc. 
The next important feed requirement for the 
laying hen should be a mineral feed of some 
kind. With many farm and city flocks this im¬ 
portant consideration is entirely ignored. Many 
times the reason for poor egg production rests 
solely in the lack of proper mineral foods. 
When it is considered that about 12 per cent 
of the entire egg is composed of shell material,
