Ducklings losing feather at that age is normal, although it does look like a lot of feathers missing along her neck. Have you noticed her scratching it? Have the other ducklings been pulling the feathers out? Do they have any Mites/Lice on them?

What does the feeder look like?
Are they maybe rubbing the area raw on the edge of the feeder or water dish?

I spend a lot of time with them and haven’t noticed them bothering it at all or the other ones. No mites or lice either that I can see.. it’s more visible after they swim. Can the red be caused by it being to warm in the brooder ?

Ducklings have red skin, It can become more redder if it becomes inflamed or irritated.

Could it be the water when I let them swim? I put them in my bathtub with warm water because I didn’t want it to be to cold for them

Do they stick their heads through that feeder's hole?

Yes, it only about an inch deep

They could be rubbing their heads along the hole like @21hens-incharge suggested. Try switching to a bigger feeder and see if that helps.
