It has to be replaced frequently due to Nitrogen build up
What is the purpose of a heat lamp?
mimic brooding, as chicks go they require a higher temp
What does length of heat depend on?
season; brooding in summer (2 weeks) and brooding in winter (3 weeks)
How has the kind of poultry meat produced changed overtime?
decrease in whole chicken, increase in cut up and further processed
What can chicken litter be used for?
fertilization, biogas generation, (and something else idk)

Iowa, Ohio, Indiana, Pennsylvania
Do all egg laying chickens produce the same amount?
no
On average how many eggs do laying hens produce a year?
250
What is done to the beaks of laying hen chickens and why?
beaks are trimmed to prevent cannibalism
How is molting induced?
fasting and reducing the daylight
What happens when chickens molt?
stop laying eggs
What is molting in the wild?
chickens shed and regrow feathers in the fall as daylight decreases
What does molting improve?
egg laying rate, shell quality, and albumin height
How are laying hens kept? Why?
in cages to reduce exposure to disease and keep eggs cleaner
What are the types of laying hen systems?
conventional battery cages, enriched colony, aviary
What is the name of the group that investigates egg laying facilities?
Coalition for Sustainable Egg Supply (CSES)
What are animal care issues?
Study methods, Commercial setting, Sample size, required multiple years, very expensive
What are characteristics of conventional battery cages?
indoors, climate controlled, multi leveled, 6 hens per cage, eggs roll down
What are characteristics of enriched colony?
indoor, multi level, wire mesh floor, wider space than battery cages, allows chickens to express normal behavior
What are characteristics of an aviary?
free range, no cages, indoors, climate controlled, open space and multiple levels to allow for natural behavior
What is incubation?
warming egg and turning it so that developing embryo develops and also doesn’t stick to one side
How many US households own bird?
7.9 million
How many birds are owned at pets in the US?
20.3 million
What is the accepted hen mortality rate?
5%
Which laying facility has the highest mortality rate?
aviary
What is Campylobacter spp.?
the most common bacteria that causes diarrhea
Why do aviaries have a high mortality rate?
Campylobacter spp.
What laying facility is best?
Enriched colony
How is the enriched colony being the best facility a compromise?
improves welfare with the fewest problems with sustainability
Why is free range not sustainable?
it will not meet the demand for food, and we would need for land and resources than we have access to
What is the function of the infundibulum?
egg pickup, sperm storage, and fertilization
What is the function of the isthmus?
formation of shell membrane

egg shape/size, double yolk, double shell
What is the purpose of candling?
see if egg is fertile, looking for germinal disk

less
