chickens runny noses acting healthy

[samx]

age: their ages young around 2 or 3 months no more then 6 months.
length of time sick: around two weeks give or take.
symptoms: clear runny nose one sneezed once or twice.
how are they acting: same a always. healthy acting runnig around eating and drinking normal. will use me as purch if a bind down to pick up something.
treatment so far: nothing just feeding and watering.
treatment willing to try: something i can do myself. dont have a lot of money for a vet. I am not willing to cull them these are my babies i raised since they were around a couple days old.

They had a big change in the last month. They have moved out side with our older flock that are around 3 months older. They seem to have adjusted well. The weather is hot around 95-110 degrees each day and around 80-90 at night. So it is dusty we are in severe drought. The reason i bring this up is i was wondering if they can have runny nose from hot and dusty weather. Any help would be wonderful. I can answer any questions about them that will help.
they are buff orphingtons and one easter egger

The only thing I can think of to do as a precaution in case they are getting sick is to give them a b12 vitamin supplement in their water,other than that keep a close eye on them
