I'm so sorry to hear this!! I wish there was some way for you to figure something out. When I only had one horse, I kept it at a different barn. In exchange for board and food, me and my sister cleaned the barn (they had anywhere from 4-7 horses at at time) but when we got a second horse, we had to start paying. Maybe you could work something out like that?? I know just cleaning the barn wouldn't cover all the fee's but maybe knock a few dollars off, and maybe you could offer to do something else for them...??
