When chicken eggs start to develop, the white part changes and forms new protein teams that might help the baby chick grow — not because of food, but because these proteins are changing and working together in new ways.

When chicken eggs are warmed up to hatch, the white part of the egg changes and forms new protein teams, including one with a protein that binds RNA. This suggests these teams might help the baby chick grow, not just feed it.

Similar Assertions

When a chicken egg is fertilized and starts to grow, something special happens after day 14: a protein called ovalbumin moves from the egg white into the yolk, but this doesn’t happen in unfertilized eggs. It’s like the growing chick is pulling nutrients from the white to help itself grow.

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.

When a chicken egg starts to develop, the proteins inside the egg white change differently depending on whether the egg is fertilized or not — the embryo seems to change how these proteins break down and stick together.
