Flock starting to get respiratory problems

[chuckwagon1971]

I live in Florida, and recently we have gotten major amounts of rain. Seems like my chickens got a respiratory disease. I normally use Tylan and inject the sick birds, but I have about 80 birds and need something to put in water or food that will get to all the birds. Any info is appreciated

You can use Duramycin soluable powder which should be available at any feed store. The tylan soluable powder has a 1 day withdrawal period, duramycin is much cheaper than the tylan, but has a 21 day withdrawal period. I hope you realize that injecting antibiotics are more effective than using antibiotics mixed in water. Additionally duramycin is less potent than tylan.
Your other option is to cull sick birds, if you dont this will be an ongoing problem for you $$$. Rains dont cause respiratory diseases. They are normally produced by a sick carrier bird introduced into a healthy flock and easily spread. Of course a wild bird can introduce something as well. Most diseases can also be carried on clothes, your hands, shoes etc...from handling a sick bird at a swap meet for example. Then going home and handling your healthy birds.
