The Hatchery Flashcards
where do hatcheries get their eggs from?
they use their own breeders, the eggs are washed and stored (cooled to 55-65 to pause the pregnancy) and shipped to hatchery
define oviparous
egg pregnancy
72 degrees F
physiological zero, you will begin to see changes in the egg
hatchability… math
given order number and % hatchability
–> divide given order # / % = #of eggs to order
(multiply by 2 for layers and turkeys, want females)
*always round up
In ovo vaccinations
in egg vaccine
-chicks are born with the vaccinations
-computers, reduce human error
spray vaccines
after the chick is born
-works great for infectious diseases
brooding birds
use brooding rings, heat in the middle with water and food distributed evenly
–> decrease the temperature each week
functional pikotherms
chicks have varying body temperatures, they are bad at maintaining their own body heat
–> ideally 90 degrees F
What temperature will pause pregnancy of the egg?
55-65 degrees F
How long is the incubation period?
21 days
