Spring grass = Excitable Legacy

I When the spring grass comes through each horse can react to it differently, some put on weight, and others can get quite excited. Legacy can be quite excitable just on a day to day basis, because of this she's on Naf Magic calmer (can review this is people would like) this stuff is what it says in its name magic, she's just so happened to run out of it as the fresh grass is coming through. 

From the way she's been while she's off it, I can't wait until she's back on it haha. 

As she's slightly still too underweight for my liking, she's been on Baileys topline conditioning mix and Dengie healthy tummy, both of these together have worked well for her but as she isn't getting worked much due to me not driving yet she hasn't been using up her energy. 

Original energy + Spring grass + Extra energy from feed = Explosion of Legacy. 

Because of all of this she has now been taken off her feed for the summer Atleast and she will now have a forage based diet, but I need to find a balancer for her to also have. 

If anyone has any recommendations on a great balancer that can be fed along with Naf Magic that would be great.
