8 POULTRY LABORATORY GUIDE 



one is the simplest, which one trips the easiest, 

 the quickest, and makes the surest catch ; also 

 which one is the easiest to register the layers, to 

 collect the eggs, and reset. 



Drinking fountains. — Note the different 

 shapes of fountains, how the water is held in 

 them, and how it is kept clean if the vessel is open. 

 Note the different materials of which they are 

 made, also their construction with reference to 

 ease and thoroughness of cleaning and quick- 

 ness of filling. Are they placed on the ground, 

 on a raised platform, or are they suspended or 

 hung from the side of the wall ? Which is the 

 best ? What provisions are made, if any, for 

 keeping the water cool in summer? 



Feed hoppers and troughs. — Note size, shape, 

 and method of construction, kind of material 

 used, and how attached to the wall. Examine 

 carefully and study methods used to keep the 

 birds from wasting the dry food. 



If wooden or metal troughs are present for 

 feeding wet mash, note size and shape, also what 

 method is used to keep the birds out of the 

 trough and of keeping the food clean. 



All food hoppers should be so arranged that 

 they can be easily taken out of doors, emptied, 

 cleaned, and should be so constructed that the 

 birds will not waste or soil their food while eating.
