This last weekend we had the opportunity to watch chicks being born.  It was an exciting thing to see that first little pip and a chick bursting forth out of its shell.

We also did some experiments prior to the hatch.

1. Rubber egg  

What you need is one raw egg, one jar, and vinegar.

Gently place the egg in the glass jar.

Slowly pour in the vinegar until the egg is completely covered.

Store jar covered for at least 72 hours to a week. The longer the better

Then i had my children guess what would happen to the egg.

What does happen to the egg?

The vinegar causes a reaction with the calcium carbonate (the chemical that makes up the shell) breaking it into its calcium and carbonate parts which releases the carbonate in the form of carbon dioxide. You can see this reaction taking place almost right away in the form of carbon dioxide bubbles forming on the egg . The calcium part is left floating around in the solution. 

Some of the vinegar will also sneak through the egg’s membrane and cause the egg to get a little bigger.

You can see here on these eggs the leftover calcium after the carbonate separated.

Then we decided to see how far they could bounce before they broke.My son’s egg didn’t make it very far only a few inches. My daughters egg on the other hand made it to about a foot before it broke.

The second experiment we did was to test the strength of an egg.  This one was super easy. We just need one raw egg.  I then let each child squeeze each egg as hard as they could with one hand.  The egg does not break. Why?  The shape of the egg is what give it such strength. Eggs are similar in shape to one of the strongest architectural forms,  a 3-dimensional arch.  The curve the shell distributes pressure evenly all over the shell rather than just one part. By putting your hand around the whole egg the pressure of you squeezing it is distributed evenly all over the egg. However, eggs break easy when uneven forces are applied,  like when you crack it on the side of a bowl.   This is how a hen can sit on an egg and not break it (the weight of the hen is evenly distributed over the egg)  but a tiny little chick can break through the eggshell (the pecking of the chick is directed at just one spot on the egg)

The third experiment we did was to see how a chick breaks through its shell.  We just used a raw egg and an opened up paperclip.  I let each kid try to scrape through, without poking it directly into the egg.  It takes a long time, and their hands and patience with this experiment grew tired. They were then able to understand and appreciate the hard work it took for the chick to break out.

Now for some super cute pictures of our chicks! We had a total of 7 chicks hatch. Three did not make it.

The only black tufted chick that hatched. Look at those tufts!

Blue double tufted.

Clean faced lavender chick 

This breed of chicken defiantly lives up to its difficult name so far.  Out of 26 eggs 7 hatched and 4 survived, 2 tufted and 2 clean faced.  This whole experience of hatching always makes me in awe of the power of our living God and savior who makes all things.

Thus says the Lord, your Redeemer,
And He who formed you from the womb:
“I am the Lord, who makes all things,
Who stretches out the heavens all alone,
Who spreads abroad the earth by Myself..”

Isaiah 44:24
