How does penicillin differ from Terramycin?

[the Old Rebel]

I should know all of this by now, but I don't. I know some people don't think Terramycin works, but it has done wonders for me for 10 years. Still, someone suggested that I give my roo that was attacked by a weasel some penicillin. I don't have that on hand, but do have Terramycin. Can someone tell me what the difference is??

I'm on my way now to get a penicillin injectible, but would rather give the bird antibiotics by mouth, if possible.

I'll appreciate any and all help y'all can give me.

Hope you have a GREAT DAY!!
