My 20 Days Old Baby Budgie Jumps Out Of Nest

My 20 days old baby budgie jumped out of the nest, i keep putting him back, but he keeps jumping. He is okay, and the parents keep giving him food, should i worry, or keep trying to pit him back? His older brothers or sister are almost 30 days old, they have all the feathers and they just dont jump! Is that normal?
