Turkey can't fight back :(

So this happens quite a lot when i hunt turkeys with my halberd (not sure if it happens with any other weapon). I hit a turkey, and it runs towards me and then it stops like 1 tile away from me and keeps doing the running animation but not actually moving, and not attacking, it simply bugs out and starts teleporting in a radius of about half a tile towards, and away from me as if it is spazming (not sure if it's spelled like that).
Here is a screenshot of it doing that, altough you can't see it spazming cuz it's just a screenshot.
