GLW with attitude issues

[BARobbins]

I would appreciate input from those experienced...
I have a GLW that has been the aggressor for some time especially when it comes to food. Recently my SLW has really been getting it from her, last week I found a spot on her head behind her ear where it was bald spot. I put some blue cote on a cpl. times to hide and medicate(BTW that dye!!!) Now I am seeing her chase down the SLW all over the run and then another will seem to join in. I have separated her for a few hours during the day between the runs and everything is calm. I am contemplating putting in a 5x3 wire kennel we have for infirmary use in the main run with some shading and a lil roost. Hoping after a cpl/few days separated but still around it might calm her down? Do I need to also make sure no line of sight? Sorry for the diatribe just looking to restore order without harsher actions.
thank you!

I'd remove her completely for a week or 2 to reset her position in the pecking order

That would help. Multiple feeders spread around with clutter to block line of sight helps a lot with food guarding issues.
