sneezing chicks. HELP

[shellybean40]

My chicks are sneezing up a storm in the brooder. I am giving them duramycin in their water. They are 2 weeks old, from Tractor Supply. I see no swelling on their faces, they are eating like crazy and drinking, also. Is there anything else I can try or do I let it run its course??

I also got some chicks from Tractor Supply this year and all of mine but one speckled sussex died. I started giving them duramycin and vitamins and electrolytes in there water and like I said all but that one died but I got more later on from TSC and only a couple of them died. Really dont know what else to recommend you to give them wish I could be more help. May just be the hatchery that TSC is getting there birds from.
