Aside from leveling the "spare" horses. A lot of people like to level Tier 1 Mustangs when they have extra space.

This is because Mustang are the lowest quality horses that actually still give diamonds at level 15 even for Tier 1.

Ok I know it's not a lot of diamonds but Mustangs are very very cheap to breed for T1 and likewise the training is also cheap at approx 4 training sessions to reach level 15. This means that you can train a T1 mustang in the space of 1 day from level 1-15 and pocket 20 diamonds. Do it with 5 for example and that's 100 diamonds a day. We refer to this as "Mustang farming" and a lot of high levels will do this en mass to replenish diamond amounts.
