I Order mine in to my local feed supplier as i was travelling miles to get it, have you got any feed merchants local you could ask if they will order for you
Calm and condition is a good feed, I used to give it on my TB mare I used to own. Have you looked at Baileys Top Line conditioning mix/cubes. If you email Baileys asking for advice they get back to you really quick.
i used to use calm and condition,then i used baileys top line cubes on my highly stung tb mare and i have now moved on to top spec cool and condition and she lloks amazing and is a much calmer girl now.
I use Baileys No4 conditioning Cubes as they are barley-free like the calm and condition. My feed-anything-heating-and-he-goes-nuts TB was on C&C and is now on Baileys No4 and there has been no change in his (calm) behaviour.
