HATCHING RUNNERS ARTIFICIALLY.' 



Hatching ducks with incubators has always been more diffi- 

 cult for most workers than the same processes with hens' eggs. 

 At least half the Directors of the Cumberland Club, and probably 

 more use incubators and brooders year after year, in handling the 

 Runners. This indicates that success is possible, with the right 

 care. 



Mrs. Geo. W. Church, while admitting that it is a more diffi- 

 cult problem than hatching with hens, says that she gets good 

 hatches and that those to whom she has given directions report 

 excellent results. But she thinks many house cellars are too 

 dark, damp and illy ventilated to give best results. The first 

 move is thorough disinfection with a good modern disinfecting 

 spray, such as zenoleum, after the machine is well warmed. The 

 trays are at once filled and put in place while the machine is yet 

 moist and filled with disinfectant fumes. 



Temperature is kept at 103 degrees throughout the hatch. 

 Especially during the first week, this point must not be exceeded. 

 In case it gets too high, the doors are opened, trays pulled out 

 a little, eggs cooled to 100 ; when the trays are replaced, doors 

 closed and regulator adjusted. After 48 hours, the eggs are 

 turned twice a day till they begin to pip. Each morning after 

 they have been turned they are moistened thoroughly with a brush 

 or cloth dipped in water at 110 degrees, and at once returned to 

 the machine, no further turning or cooling being given. If the 

 machine is in a dry room, the eggs are moistened also at night, 

 after the 18th day. 



Dead and infertile eggs are removed when found, tests be- 

 ing made on the 7th, 14th, and 21st days. Any giving off bad 

 odors should be at once removed. 



Ventilators are left wide open till the eggs begin to pip, and 

 are then closed to one-fourth inch. With enough moisture, the
