1 chicken sneezing? and 1 with a bit of a snotty beak

[aafairchild]

These 2 out of 7. No other symptoms. All birds are eating drinking foraging as normal. Is this something to panic about or will it run its course? If time to panic how do I treat? Freaking out a bit as new babies are being shipped tomorrow and am concerned about cross infecting the newbies. All are 7 weeks to 3 months. No goop on sneezer and goop on roo is dry. They are eating fermented feed, but my mom said they sounded a bit congested. They seemed fine to me. Pine shavings for bedding.

Thanks
Alice
