how to get hard eggs

Egg production does drop when it gets near winter because of the shorter daytime hours and light, which is why some chicken owners decide to put light in their coops during fall or winter. I prefer giving my hens a rest from laying in the winter.

 

I don't know about making the shell harder, make sure there is a good amount of calcium in their diet, because that is what makes the shell hard.

My boys did this in kndergarten, no grade, I helped my second son, we put the egg in a box, padded with polyfill, then taped styrofoam around the box, and made legs to cushion the impact, and the egg survived.

 

I did that in 5th grade. Got an A. Remember, the egg doesn't break in the fall, it breaks in the landing. I had the egg suspended in a sling that was hooked to each end of the box. it had enough room to move around without hitting the edge. Imagine a bungee jumping egg. That's what you're going for.

 

how to get hard eggs? Boil them longer????

 

Your project isn't about how hard the egg shell is, it's about cushioning the egg.

 

Do the rules specify that it has to be a chicken egg? Have you thought about using a Guinea egg? Their shells are a lot tougher to break than a chicken egg.

A guy I bought hay from once was telling me his daughter had to do this same project. She used a Guinea egg and it didn't break. She got and A.

 

Buy guinea eggs online if you're unable to find locally. You can buy just about anything online. My pekin and mallard eggs are pretty tough as well, reptilian like
