There is no one answer to that question. It's dependant on too many things, such as the season and weather temperature, the size and eating habits of your horse, as well as how much other grazing or food he or she is getting and if they have unlimited, 24-hour access to the round bale, (which is not recommended) Generally, (and this can vary quite drastically) one round bale of hay will last an average sized horse 5 - 6 weeks. Two horses - about a month or so, Three horses - about 2 1/2 to 3 weeks, etc. *This is assuming that the round bale does not get ruined by rain and the horses urinating and defacating on it, etc.
As long as necessary. To Satisfy the appetite.
It would take 12 bales of hay!!!
Go guitly and slowly round it on the outside
As long as it takes for you to master the art of riding a horse.
Depends what you do with it.
it would take a long time even if you are on a horse they can and will get tiered they will need to drink some water and stop for a brake.
a long time lol
A long time
It depends how much the horse weighs and what breed.

Spelling a horse means to take it out of work for a while,to have a brake of riding and stuff.Kinda like a long holiday for a horse
Depends on how fast the horse is going.
