Thanks for all the ideas guys! So I'll definitely go for the home made treats since that seems to be the biggest hit. I'll probably end up doing some of the others too since I like to go overboard sometimes lol. I came up with another one too. Every tiome the farrier comes I feel like I should take the horses' old shoes and do something with them but I didn't know what. Today I came up with making dream catchers out of them. So next time the farrier comes I might actually take the shoes and make up a few.
