How to collect horses working in other riding scho

Hi all, I put few horses to work on a stable that is not mine, and now I can´t find them to collect the money, EXP and objects. Where is the option? Thank you.

On your horse's page under this horse is owned, bred by, and then before the picture there is a line that says "This horse is currently working at a Riding School. Visit?" 

Is this what you mean?

I think yes, thank you.

Is there any other way to get there? I mean, if I enter horses in school but not the same horses everyday, and I forget which horses I put on the riding school, should I check one by one to see which ones were working at the riding school?

Not to my knowledge unless you remember the owner or riding stables. It is easier to put them all in the same riding school or I group them by specialty. It's kinda like there is no way to view what horses you have in shows unless they haven't run yet and you remember the horse you entered or you wait to see the results? 

If you're not a sub you have to go through manually each day and water and feed so I have to look at every single one, every single day. I could do it that way if I had to do them individually. 

Do you enter them individually? I guess I pick horses I think would do well in shows first and then go through and enter everything else in riding school. 

Thanks :) I enter all of them in the same school. I will write some notes to remember the school, then :) Thank you!
