No luck selling horses

I  have made some big changes! So, first off, with my own horses, I have made my standers a little tougher. AND, when a horse just does not seem to sell, i will retire it early. I know it might not make sense, but, it will give me more room for more horses and such.

I have also started showing all of my horses, which hopefully will start bringing in some more money. If they don't do good in shows, i am going to do like wey said, put them in riding school. Thank you all for the great advice! It has really helped me, and I will now be a little more picky when taking in new horses. But will make exceptions for those that need it. 

Thanks everyone!
