where to buy antibiotics?

What's the best place to buy sulmet or tylan 50? I found the tylan 50 but it's injectable. Where do you find the one to put in water? My flock is getting breathing problems. Will they ever get better to lay eggs or do I have to start culling?

I get mine at Tractor Supply Company
