CHAPTER XI 



ARTIFICIAL PROPAGATION 



By Gardiner Bump 



ORIENTATION 



Background and Difficulties — Methods of Raising Grouse — Progress to Date — 

 Results 



THE STARTING POINT 



Eggs from Wild Nests — Collecting and Transporting Grouse Eggs — Wild-Trapped 

 Birds 



THE NATURAL COVER METHOD OF RAISING GROUSE 



Penning Birds and Providing Shelter — Feeding — Protection from Predators — 

 Danger from Disease — Vitality 



THE INCUBATOR-BROODER METHOD OF RAISING GROUSE 



Caring for the Breeding Stock — Overwintering Grouse Breeders — pens and penning — 

 foods and feeding techniques — handling the spring shuffle — weight and physical well-being 

 — The Spring Period — selection of breeding stock — breeding pens and equipment — pen- 

 ning and care of breeders — feeding breeding birds — mating and egg fertility — egg pro- 

 duction and collection — controlling disease — The Summer and Fall Period — moulting and 

 recuperation — The Incubation of Grouse Eggs — Grouse Mothers — Foster Mothers — 

 construction of hatching coop and nest — care of eggs — -The Incubator Method — location 

 of the incubator — type and care — incubator operation — measuring incubation progress — 

 setting and care of eggs — hatching and transfer of chicks — Brooding of the Chicks — 

 Brooders and Brooder Houses — Brooder Operation — Care of the Chicks — Feed and Feed- 

 ing Techniques — Feather Picking and Cannibalism — Reducing the Danger from Disease 

 and Predation — Rearing of the Young Birds — Rearing Fields and Units — Pens and Pen- 

 ning — Feed and Feeding Techniques — Disease Prevention and Control — Care During 

 Rearing — The Period of Social Adjustment. 



PRACTICABILITY OF ARTIFICIAL GROUSE PRODUCTION 



Production Equations — Factors Limiting Production — Biological Limitations — 

 Scarcity of Obtainable Breeding Stock or Eggs — Lack of Trained Manpower — Cost
