- Chickens can make helpful proteins in eggs.
- Scientists want those proteins to stay active.
- New inserted traits can turn off later.
- This problem stops steady egg production of proteins.
- Researchers used a lab method to place traits.
- They added a green marker to watch.
- Cells kept glowing after many divisions.
- The glow showed the trait stayed active.
- The goal is stable bird lines.
- Stable eggs could help people and farms.
