Which egg is fertile?

Which egg is fertile? The egg I circled is fertile because it’s germinal spot is larger and it contains both male and female parent cells.

The fertilized egg is formed when male and female cells unite during mating. They are fertile. They are Leghorn eggs. The color of the shells are white. X X X The air cell looked like a dime. The temperature of the incubator is 99 – 101 degrees F. Page 11

Water should be added to the incubator every day. We should turn our eggs five times per day. We observe embryos by candling. I helped with the project by… Page 12

Draw what you see in your 21 Hatch Day!! Write your own fact about what you see. Draw what you see in your incubator.

Preparing for Hatch Day Day 18 - Friday Stop turning the eggs Fill tray #2 with water Bunch the eggs together in the incubator Prepare the Brooder Box What’s a Brooder Box?

Expectations for Hatch Day Day 21 - Monday Peeping Pip holes Cracks, hatching Blood, fluids, odor Chicks! It can take from one to 24 hours for a chick to go from pip hole to fully hatched. BE PATIENT!

Hatch Day Rules Your teacher will move chicks from the incubator to the brooder box. Monitor chicks to be sure they are not too hot or too cold. Chicks rest for 10-24 hrs after hatching before you may hold them.

Be Gentle…Be Quiet…Be Calm Rules for Holding Chicks Wash your hands before and after holding chicks. Sit on the floor and hold the chick against your belly. NO STANDING. NO CHICKS ON DESKS, TABLES OR THE FLOOR. Do not wake a sleeping chick. Do not hold chicks if you are sick. If your chick escapes, remain seated and calm. Your teacher will capture your chick. Be Gentle…Be Quiet…Be Calm
