You could ask your vet if she thinks you are feeding enough, its hard to say without knowing the weight of the hay. You could always add a fat supplement to their diet like ricebran- its very inexpensive and it will give them shiny coats and add extra calories without making them hot.
Do they get hay only or hay and a grain? If they are on hay only they may be lacking in certain minerals etc if not on a supplement. You can always have the hay tested and see what its missing.
As much as no one wants to hear it, if what it takes is more food and its not in the budget, it may be in the horse's best interest to downsize the herd so they can all be at a healthy weight.
Best of luck!
