Any ideas to help with feather plucking?

[Deltain]

I have a single hen with a bald spot on her lower throat/upper chest area. It's not bloody or anything, but the rest of the ladies won't let it regrow. Is there a chicken bib? A bandana? Something to cover up the spot long enough for the feathers to grow past "pick at this" range. Thanks y'all!

i was thinking and maybe you could make something like a chicken saddle but it also has a part that gose over her chest? Or a little bib that comes off a harness. Good luck.

Can you get blue cote? Feather picking is a sign of other problems, like not enough space or protein.
