Value of dry mash, green food, grit, shells, charcoal. Why a 

 scratch feed? Why have a variety? Quantity of feed needed? 

 How obtain succulent food ? How provide water? To what extent 

 shall wet mashes be used? How feed the layers and the breeding 

 flock? Avoid diseases of the digestive tract. Avoid spasmodic 

 feeding of green foods which leads to overeating. Feed hopper 

 approved by the U. S. Department of Agriculture is shown in figure 8.

 State agricultural college 

 bulletins are especially val- 

 uable on feeding. 



Home projects . — H a v e 

 each pupil arrange for feed- 

 ing his flock rations which 

 best fit his own circumstan- 

 ces, considering the availa- 

 ble home-grown feed, local 

 prices of grain, supply of 

 table scraps or other by- 

 products to be obtained. 

 The purpose of the flock 

 should be kept in mind as 

 well as the relative protec- 

 tion from the winter's cold. 

 Have feed records kept 

 constantly and reported 

 occasionally. Weight 

 should not be estimated. 

 Labor record should be 

 kept. See record forms, 

 pages 26-32. 



Material and exercises. — 

 Have samples of as many 

 poultry foods as possible 

 brought to school. Classify and study these and arrange them for the 

 permanent school collection. Have some members of the class post each 

 week the fist of prices of all the grain and other feed for poultry, using 

 local retail prices. Make a list of home-grown feeds and give the price 

 at which the farmer might sell each. Change this list as prices change. 

 Correlations. — Compute the cost of different rations used. More 

 mature pupils may compute the balanced rations, but so many mix- 

 tures have been computed by experts that it is not necessary for the 

 amateurs to learn this detail.
