How much you've bought your horse and how much you earn daily?
For a single horse you can earn 300 to 600 vis daily. Not guarenteed but the few days Ive noticed this is the range where I could earn vis on a daily basis. You can do the income computation or estimates.
Nice, you're already in profit if you want to sell it to the market. AFAIK, there's free breeding with those horses that have been purchased for this week. I still don't know the whole thing and I wish that whoever bought it this time will be able to make really good money from it.
I dont know this free breeding you mean. You could consider me as one fo those who risk. Anyway I'll update my status if Im gonna win on this thing or atleast profit or roi on the case.
