I used Pen on my bird that was attacked by a hawk.  I got it from the fridge in a grain store.  I believe it said the same thing.  For some reason most chicken meds are necessarily made for chickens but other livestock.  You just have to get the dosage rite.  I have always had better results with injectible meds for some reason just because you can't always guarantee the bird is getting the proper dosage.  Of course I never medicate unless absolutley necessary but in this case it worked.
