What antibiotic for infected preen gland?

[Tacswa3]

I have 4 muscovies I rescued and I'm pretty sure their preen gland is infected. Anyone know what antibiotic can be used for it?

Have you tried milking the gland?

I did for the male when I tried bathing him. DO NOT under estimate the strength of a large muscovy male. When the muscovies wag their tails, I can see the gland. Yellow staining at the gland. Their symptoms also match what is described when a preen gland is affected.

I think it would be unusual for all four to have infected glands. Can you post some pictures?That
