She looks very similar to my boy and he was given a condition score by Spillers feed nutritionists of 5.5 on the 1-9 scale (so probably a 3.5 on the 1-5 scale). He doesn't get much in the way of hard feed - just a balancer and a handful of chaff. He is being brought back into work as he hasn't done much for the last 5 months and I think I am beginning to see a change.
