3 DUCKS EGGS SET 3/17/16 HATCH 4/14/16

Round 2

6 DUCKS EGGS SET 3/26/16 HATCH 4/23/16





New Way To Hatch And Grow An CHICKEN Embryo

Experiment #1 Chicken embryo in a dish
I have done this before and it lasted a week it was really neat watching it move and grow.

Experiment #2 Window View Egg
I have had success doing this many time, you take off the shell where the air cell is and cover it with plastic wrap and you can watch it grow without the shell and even watch it pip and hatch!!!

Experiment #3 2004 Original Experiment
Growing up before I had an incubator I used a heating pad but wasn't allowed to have it on at night. never really had a chance and try it since I didn't know anyone that had fertile eggs.
I'm going try and see what happened when I take the egg out of the incubator at night until I wake up in the morning and put it back in to see how long it would still grow and live, just like it would of been if I had fertile eggs back in the day and tried it. (starts on day 7)

I will be coming up with other ideas too while all this is going on.
if you want be to try any of your idea just let me know

Day 1:

6 to 10 h - First kidney-like cells (pronephros) begin to form.

8 h -Appearance of primitive streak.

10 h -Yolk sac (embryonic membrane) begins. Functions include: a) blood formation; b) yolk digestion; c) yolk absorption; d) food provision after hatching. Mesoderm appears; embryo oriented at 90° angle to egg's long axis; mesonephros begins.

18 h -Primitive gut begins; primordial germ cells appear in germinal crescent.

20 h -Vertebral column begins.

21 h -Appearance of neural groove, nervous system.

22 h -Appearance of first pair of somites (block-like segments) and head.

23 to 24 h -Blood islands, vitelline (yolk sac) circulation, blood, heart,blood vessels begin (2 to 4 somites).

Day 2:

25 h -Appearance of eye; vertebral column visible; embryo begins to turn on left side (6 somites).

28 h -Ear begins (7 somites).

30 h -Amnion (embryonic membrane around embryo) begins. Primary function is to protect embryo against shock and sticking; also responsible for some albumen absorption. Chorion (embryonic membrane that fuses with allantois) begins; heartbeat begins (10 somites).

38 h -Cranial flexure and torsion evident; heartbeat moves blood (16 to 17 somites).

42 h -Thyroid begins.

48 h -Anterior pituitary and pineal glands begin to develop.


Day 3:

50 h -Embryo turns on left side; allantois (embryonic membrane that fuses with chorion) begins. Functions of chorioallantois are: a) respiration; b) albumen absorption; c) absorption of calcium from shell; d) storage of kidney excretions.

60 h -Nasal pits, pharynx, lungs, anterior limb buds begin.

62 h -Posterior limb buds begin.

72 h -Middle and outer ear, trachea begin; amnion completes growth around embryo.


Day 4: Tongue and esophagus begin; embryo separates from yolk sac; allantois grows through amnion; contractions occur in amnion wall; adrenal development begins; pronephros (nonfunctional kidney) disappears; metanephros (definitive or final kidney) begins; proventriculus, gizzard, ceca, large intestine begin. Pigment visible in eye (dark eye).


Day 5: Reproductive system and differentiation of sex appear; thymus, bursa of Fabricius, duodenal loop begin; chorion and allantois begin to fuse; mesonephros begins to function; first cartilage present.


Day 6: Beak appears; voluntary movement begins; chorioallantois (chorion fused with allantois) lies against shell near large end of egg.


Day 7: Digits appear; comb growth begins; egg tooth begins; melanin produced; absorption of mineral from shell begins. Chorioallantois is attached to inner shell membrane and growth around the inner surface is progressing.


Day 8: Father tracts appear; parathyroid begins; bone calcification begins.


Day 9: Growth of chorioallantois about 80% complete (still open at small end); mouth opening appears.


Day 10: Beak begins to harden; digits completely separated.


Day 11: Abdominal walls established; loops of intestine begin to protrude into the yolk sac; down feathers visible; comb and wattles visible; claws and scales appear on toes; mesonephros reaches maximum level of function, then begins to degenerate; metanephros begins to function.


Day 12: Chorioallantois completes enclosure of egg contents; embryo water content begins to decrease.


Day 13: Cartilaginous skeleton is relatively complete; embryo heat production and oxygen consumption begin to increase rapidly.


Day 14: Embryo begins to turn head toward large end of egg; long bone ossification becomes rapid. Turning of egg no longer essential.


Day 15: Intestinal loops easily seen in yolk sac; contraction of amnion ceases.


Day 16: Beak, claws, and scales relatively cornified; albumen is practically gone and yolk increasingly important as food source; down feathers cover body; intestinal loops begin to retract into body.


Day 17: Amniotic fluid decreases; embryo positioning head toward large end, toward right wing with beak toward air cell; definitive feathers begin.


Day 18: Blood volume decreases, total blood hemoglobin decreases. Embryo should be in proper position to hatch: embryo's long axis the same as long axis of egg; head in large end of egg; head to right and under right wing; beak pointed toward air cell; feet toward head.


Day 19: Intestinal loop retraction complete; yolk sac begins to enter body cavity; amniotic fluid (swallowed by embryo) disappears; beak may pierce air cell and lungs begin to function (pulmonary respiration).


Day 20: Yolk sac completely drawn into body; air cell pierced, followed by functioning of pulmonary respiration; embryo makes sounds; chorioallantoic circulation, respiration, and absorption decrease; embryo may pip shell.


Day 21: Hatching process: chorioallantoic circulation ceases; embryo breaks shell over air cell with egg tooth; embryo slowly rotates in egg counterclockwise, chipping and breaking shell as it does; embryo kicks and attempts to straighten neck, pushes shell open; kicks free of shell, rests, straightens, dries.


> Day 21: Some embryos are unable to hatch but survive beyond the normal hatching time
