If possible do this tame in a 2 section building, one part troodon, one part your creatures, and whenever the troodon is hungry, move one of your dinos from your section to its. I also recommend doing this on a platform saddle
At lvl 72 with flak armor on, a lvl 5 Troodon knocked me out with one attack at night. Last thing I saw was those glowing eyes before passing out. My Guess is that they attack vital organs. Luckily my Doedicarus was up for a game of baseball and launched that little devil out into the stands.
