Molt following egg-laying

[Elizabeth]

My 3-yo cockatiel Lulu laid 4 eggs and tried to incubate them. She’s starting to lose interest in the nest, and in the past week has started molting - lots of flights and tail feathers.

She was long overdue for a molt but this seems very sudden.

Is this normal?

Do you think she pulled them to add to her nest?
