New,A few questions.

Hello everyone.I have now reached level 3 and would like a little help with a few questions about the game.

Q1. Do horses under 3 have to be boarded in a stable.If they're not boarded does it reduce the level in foal training.

Q2 What happens to tack when you put a horse for sale.Does it go back in your inventory or does it go with the horse.If it goes back into the inventory how do you take it off.

Q3 Do shows run daily or only when the show is full.I understand that only notifications are sent for the first three places.Is there any way to check if the shows have run.I asked this question because I am eight hours ahead of game time.Also are the notifications you do get for the shows run that day or the day before

Thank you for any answers.

Q1. Do horses under 3 have to be boarded in a stable.If they're not boarded does it reduce the level in foal training.
A1. I believe any and every horse you own must be boarded to do things.

Q2 What happens to tack when you put a horse for sale.Does it go back in your inventory or does it go with the horse.If it goes back into the inventory how do you take it off.
A2. Never actually payed attention to this. I think it goes with them.

Q3 Do shows run daily or only when the show is full.I understand that only notifications are sent for the first three places.Is there any way to check if the shows have run.I asked this question because I am eight hours ahead of game time.Also are the notifications you do get for the shows run that day or the day before
A3. Shows will run when they get full (15 entries) but each and every show has their own end time (it's the little clock that's counting down when you manually enter a horse)
Also in "Your Activity" it has the horse's name, the show, and their stats from it. If you click on the show's name you can see all of the other placements in it.

For your second question, yes, tack goes with the horse for sale! if you wish to remove the tack, just click the image of the tack piece. you can do this before or during the sale of the horse, just not after, of course, since it would no longer be your horse or your tack c: 

Quick clarification re: Boarding. Foals do not have to be boarded to be trained, I'm not positive if it will affect your overall training bonuses, but it shouldn't affect actual training at this time as far as I can tell. However boarding your horse is required to train an show it once it is past the age of 3.

And to check if shows have run the only ways to know right now to know if they have is if you've gotten a notification that your horse has placed or if you search for shows for your horse to see if there are any that you entered that haven't run.
