Chicken Life Cycle

3rd grader M is hatching chicks this week in school.   I went in to school today to take some pictures of the two that hatched.  M’s younger sister K and E got a chance to meet and hold the chicks too.



Chicken facts:

  • It takes 21 days for the chick to hatch after being laid.
  • It takes 6 months for the chick to grow into an adult, after which the hen can lay their own eggs
  • Chicks will eat seeds, bugs and worms
  • There are approximatelty 175 varieties of chickens. They are grouped into 12 classes and approximately 60 breeds based on geographical areas : – Asiatic, American, Continental, English, Mediterranean
  • Not all chicks are yellow.  Some are brown, and some are black – like the Barred Plymouth Rock (check out the pictures on the right of the screen)

On double yolk eggs

From Wikipedia
“Double-yolk eggs occur when ovulation occurs too rapidly, or when one yolk becomes joined with another yolk. These eggs may be the result of a young hen’s productive cycle not yet being synchronized. Some hybrid breeds of hens also produce double yolk eggs by default. Such eggs are produced in West Bengal, India and in particular by Arambagh Hatcheries in Arambagh”

Double yolked eggs will not produce twins because their is not enough food and room for them to grow.

  2. You might be interested in an article on poultrykeeper about somebody who managed to hatch two chicks from a double yolk egg quite incredible really and I never thought possible!

    My kids are lucky enough to live on a ranch and we have chickens. You would be surprised at what all these birds will eat.
    I can throw all scraps to them from the table as long as there is no chocolate (harmful to them) or onions and garlic (makes bad tasting eggs). They especially love bread!

  5. I have hatched chicks like this with the children of my local school and they have raised the chicks in their class room. It is amazing how much interest the children show. I find it gives me enormous satisfaction doing and it is so incredible what happens in just 21 days!
