Duck having deformed shell was eggs

[Belovedturkey]

I have a duck who had a niacin deficiency a while back, and while she still has trouble walking she gets around fine but is bullied sometimes by one of my other female ducks. I noticed recently that she’s been have deformed shelled eggs but they stopped until now when she just had another one but it looks different from all the other ones. Could this be from stress, and should I separate her so she can have some time away and get extra nutrients or should I not deprecate her and monitor

Have you given her extra Calcium. I believe most give their ducks, Calcium Gluconate.
