Movie Clips - Candling Day 11



When the movie starts - here is what you'll see: This embryo is eleven (11) days old (photos below). When you watch the movie, see if notice:

  • The air sac inside the egg.
  • The 11-day old chicken embryo (see how much bigger it is than the 6-day old embryo) moving inside the egg. The movements are much stronger than the 6-day old embryo!
  • A network of blood vessels (appears orange in the light)
