Tylan 50 question.

[Jake1297]

I have two roosters that always got along great. Until the other day. Long story short, they fought, one has an eye that is now closed most likely an injury. I've read on BYC to use Tylan 50 eye drops. I have also read to put it in his drinking water.
I know Tylan 50 is water soluble. Question is: Do I put the tylan 50 on his eye with an eye dropper or is he supposed to drink it?

Thanks
