Need help with first time mama duck

[Miss Lydia]

They might mama maybe able to stop any aggression but I’d sure watch close for a while.

Ok so update:
I locked all of the flock away and let mama and her babies out to free range while keeping a close eye. She took them straight to the creek to play. They had some issues with getting stuck in the brush and had a hard time keeping up when there was large limbs to jump over but she was really patient and always came back for them to help them find a different route.
She was a good mama and I feel silly for not trusting her motherly instincts
When they were done they waddled back to the coop and she’s been much quieter since.
