DUCK RAISING ON THE FARM 



80-dozen hen egg cases by using special fillers which 

 hold 25 eggs instead of 36 as in the case of hens' 

 eggs. See page . A farmer with a small flock of 

 ducks will usually not have eggs enough to fill a case 

 frequently and for this reason he usually finds it 

 more convenient to market the few eggs he has by 

 taking them into town in a basket. 



Disease and Insect Pests. Ducks are very little 

 troubled by insect pests, nor are they greatly 

 troubled by diseases. The usual difficulties encoun- 

 tered along this line are those discussed under this 

 head in Chapter VI. Losses are often experienced as 

 the result of predatory animals. Rats will cause a 

 great amount of havoc among the young ducks if 

 they are able to get at them. A single night's work 

 on the part of one rat may practically clean out a 

 small flock of ducklings. It is necessary to make 

 sure that the ducklings are shut in at night so that 

 rats cannot get at them.
