In Europe every egg has a unique code printed on it.
For example: 0-DE-1234567
DE means Germany,
1234567 is eggs ID,
0 is the egg type. There are 4 kinds of egg types.
0: Organic eggs (Bio-Haltung)
1: Free range eggs (Freilandhaltung)
2: Indoor housing eggs (Bodenhaltung)
3: Cage farming eggs (Käfighaltung)
I designd the types of eggs to small books. Two eggs are in a special egg box. The egg box is designed in the GDR (German Democratic Republic). Let's us see the chicken's feelings with different egg types.
