                       Setting Up
• Locate a source of Fertile eggs. You can’t do this program with out a
  good source of Fertilized eggs.
• Visit with teacher(s) about setting eggs when you can be at the school
  3 weeks in a row, 1 to 2 hours each week.
• Decide if you will conduct all of the activities or if the teacher will
  teach some of them. Also discuss which activities to conduct.
  http://urbanext.illinois.edu/eggs/pdfs/worksheets.pdf This website is
  a great source of handouts.
• Determine who will bring necessary supplies.
• Get your Pre-Test ready and send to teacher.(if it is an outcome
  program)
                          Setting Up
• Be sure and Locate a source of Fertile eggs well in advance.
• Where can you get fertile eggs?
   – Texas A&M Poultry Center http://posc.tamu.edu/texas-agrilife-poultry-
      extension-specialists/youth-programs/
   – Local hatchery
   – Local producer
• Where you are located will make a difference on where you procure your
  eggs.
                Ready, Set, Grow
• Start a Chick Journal
• Week 1:
   – Set Eggs
       • Discuss Hatching Factors
           – Time (21 Days)
           – Temperature (100 Degrees F)
           – Rotation
           – Humidity (Nature vs. Incubator)
                    Ready, Set, Grow
• Parts of the Egg
   – Use real eggs to teach this. Have some fertile and non-fertile eggs to
      look at.
   – Weigh the different parts.
• The Biggest Loser
   – Ask students to write in their Chick Journal if they think that the eggs
      will lose weight, gain weight, or stay the same as the embryo grows.
        • This is a good place to teach about Hypotheses
   – Create a chart for the kids to record the egg weights each day.
               Let the Fun Begin
• Week 2:
  – Egg strength Experiments
     • How much Weight can 6 Egg Shells Hold?
     • How much weight can 6 whole eggs hold?
     • Can you break an egg with your bare hands?
     • Egg Drop
  – Egg Porosity
     • Are Eggs Porous?
                   Egg Strength
• How Much Weight will six Egg shells hold?
   – Supplies:
      • Six empty egg shells
      • Books of varying sizes
   – Procedure:
      • Set egg shells in two rows, equal distance apart
      • Start stacking books on them. See how much weight
        the shells held before breaking
                   Egg Strength
• How much weight will six whole eggs hold?
   – Supplies:
      • Six whole eggs
      • Books of varying sizes
      • Gallon freezer bag
   – Procedure:
      • place six eggs in freezer bag close together
      • Stack books on the eggs until they break. How much
        weight did the eggs hold?
                       Egg strength
• The Strong Man experiment
   – Supplies:
      • A whole egg
      • Trashcan
   – Procedure:
      • Take the egg and check it for any cracks
      • Place the egg in your hands with the ends in the hollows of your
        palms
      • Lace your fingers and try to break the egg.
      • Talk about why the egg is so strong.
                           Egg Porosity
•   Do eggs have pores/holes in them?
     – Supplies
         • Hard boiled eggs
         • Food Coloring
         • Gloves
         • Bowls
     – Procedure
         • Ask kids if the eggs have holes in them
         • Give each group an egg and some food coloring
         • Have them drip food dye on the outside of the egg
         • Wait 15 mins and then have them peel the egg.
         • Did the dye go through? Why? Discuss porosity.
               Are you in there??
• Candling the Eggs
   – Use this process to cull your eggs
   – Have the kids draw what they saw in their Chick Journal
   – Open cull eggs
   – This is a good time to study the weight chart and see who
     had a correct hypothesis and discuss why the eggs that
     were growing lost weight.
                      Chick Make-Over
•   Supplies Needed:
•   Eggs that are 11-14 Days into the incubation process
•   Regular food dye (not gel)
•   1 or 3cc syringes (one for each color used)
•   25g x 5/8in (can use 22gx1in) in needles (one for each egg injected plus a few
    extras)
•   Scotch Tape
•   Alcohol Wipes or Hand Sanitizer
•   Procedure:
•   Prior to beginning, prepare your syringes with approximately .5-1 cc of dye
•   Candle the eggs you intend to dye and remove any that are not viable.
•   Using the alcohol wipe clean a small area on the small end of the egg
•   Carefully insert the needle into the clean spot and slowly inject the dye.
•   Re-clean the injection area with an alcohol wipe
•   Cover injection hole with Scotch Tape.
•   Replace egg in the incubator.
              Preparing to Hatch
• Make sure the eggs are taken out of the turner on Day 18 of
  incubation
• Increase the amount of water in the incubator
• Use an old hand/kitchen towel in bottom of incubator to
  make clean-up much easier
                     Happy Birthday!
This is probably close to the end of your program but here are some other
   activities that you can do or have the teacher do.

• Point out the Egg tooth to the students
• If they will be keeping chicks for a little while, have them chart the weights
  of the dyed chicks.
• Have the kids teach other students what they have learned.
• Write a Chick Newspaper to send to parents, principles, etc.
