Pink eye update

Tomorrow will be the last day of treatment with the special chlortetracycline feed.  As the veterinarian said the feed is meant to stop the infection from spreading, which is what it appears to have done.  Unfortunately it appears that No. 8's left eye was too far gone by the time I started the treatment and will probably never return to a normal state.  

In many ways I am relieved to be nearly done with the treatment, which has become a dangerous event.  Because their medicated feed is mixed in with sweet feed, they've become very fond of it and will immediately come running when they see the white truck pull up to the troughs.  Their normal routine has been to mill about while I fill the troughs, but this milling has moved closer and closer with each feeding until now they only keep about 15 feet away from me.  The moment I step away they then descend on the troughs in a frenzy.  If I had to keep this up much longer I fear it would result in injury to either me or another bison.  
After tomorrow's feeding, I'll remove the troughs and put the into storage.  They've worked very well for both the insecticide treatment and the antibiotic treatment.
