chickens with a cold.

[Fussy8]

I noticed that one of my roosters crowing and sounding like he was drowning then my other Rooster had a really yucky goopy swollen eye so I called Ifa and talked to their chicken expert and she gave me this medication. It's helped everything except my icky eyed rooster still had a swollen eye... What should I do? Please help so I can stay treatment before the cold sets in!!!

What is this medication?

Chickens don't catch colds.
Respiratory illness can be bacterial, viral, parasitic, environmental or nutritional.
The first thing to look at is ventilation. Birds that get adequate fresh air and aren't "cooped up" rarely get respiratory problems.
