When chicken eggs start to develop, the main protein in the egg white breaks down in a complex way, not just into small pieces, but into special fragments that might help the baby chick grow.

Scientists found that when a chicken egg starts to grow into a chick, the main protein in egg white breaks apart in many different ways, not just into small pieces — and these pieces might help the baby chick grow. This means the egg isn’t just feeding the chick, it’s also making special helper pieces.

Similar Assertions

In chicken eggs during the first week of incubation, the main egg white protein breaks down faster than expected, and new protein groups form—including one that teams up with a molecule that binds RNA—hinting that the egg is preparing for the chick to grow, not just storing food.
