My hen has a snotty beak, should I worry?

[Desert Peep]

Shamique, my 3 month old black australorp hen has had a dirty, muddy beak with sand, and stuff sticking to it for a day or two. Today I noticed mucous/saliva on her beak while she was eating her treats (boss). She wipes her beak on hard surfaces to clean it off. Is this something I should be concerned with? She is otherwise acting normal, as are her sisters, none of which has similar symptoms. The weather has gone from warm to cool in the past couple of days; we are in southern AZ.

With our weather change one of my polish started sneezing and had a runny nose and a boogery face. I cleaned him up brought him in and put them all on sulmet. Day 3 he is much better.

Sorry for my ignorance, but what is sulmet, and where can it be purchased? Our weather has changed dramatically the past week or so from high 80's to mid 60's for daytime highs. The nights are also much cooler in the 50's. At least that's cool for southern AZ Thanks for the suggestion.

Is Sulmet better for this than Tetracycline?
