Denaguard is an antibiotic wheras Vetracyn is a "snake oil" all purpose fix everything. I am sceptical. A good diet will do the same.
I would not even use Denagard unless the birds had symptoms. No good comes from prophylactic antibiotic use. All it does is create resistance. And its very expensive
The antibiotic question came up yesterday in the socal thread, This was my reply
Sounds like I won't be trying the other stuff..but, will keep using my Denagard. Have been doing this for years, and haven't had an upper respiratory infection for about 2 and a half years.
