I was recently gifted some chicks from a friend of my sister. Once arrived, I noticed one had one eye shut, it died a few hours later after isolating. Then I noticed the other chicks had the same symptom. From 12 chicks, I now have 3 left. I started treating the remaining ones with VetRx. But I havent seen a major improvement. Just trying to see if I should continue this treatment or try another. And I would like to know what It is for future reference.
