Tylan vs Penicillin

[krazycow6]

What are the pro's and con's of either of these drugs for use on chickens. Tell me your experience with them.

Tylan is for respiratory illness. Penicillin is better for injuries and infections of the non-respiratory type. Since I have a no-treat policy for respiratory, I don't use Tylan.
