Chick Hatch 2012 Update

Some of you have been having trouble viewing the live webcam.  Here is another link to the ustream channel.  We'll be candling eggs again today around 9:00.  Hopefully, we'll be able to see a little more than yesterday.  It's still very early so all we'll be able to see is some faint blood vessels if they are developing.

During Incubation:

First day

16 hours - first sign of resemblance to a chick embryo
20 hours - appearance of vertebral column
21 hours - beginning of nervous system
22 hours - beginning of head
24 hours - beginning of eye

Second day

25 hours - beginning of heart
35 hours - beginning of ear
42 hours - heart beats

Third day

60 hours - beginning of nose
62 hours - beginning of legs
64 hours - beginning of wings
Fourth day - beginning of tongue
Sixth day - beginning of beak
Eighth day - beginning of feathers
Tenth day - beginning of hardening of beak
Thirteenth day - appearance of scales and claws
Fourteenth day - embryo gets into position suitable for breaking shell
Sixteenth day - scales, claws and beak becoming harder.
Seventeenth day - beak turns toward air cell
Nineteenth day - yolk sac begins to enter body cavity
Twentieth day - yolk sac completely drawn into body cavity; embryo occupies practically all the space within the egg except the air cell
Twenty-first day - hatching of chick

This picture below is an example of what we should be able to see by days 4,5 and 6.
