Before you even think about purchasing a new horse I would suggest getting all your supplies together. Fence, barn, health, vet, feet, brushes, food extra.. and then put aside an emergency fund.
A typical day for me with just two horses is waking up at 5:30
After that I take them both out to pasture
AM mucking out.
Bring them both in to brush them, pick out their feet.
Put them in their stalls.
Brign out Gunther for his daily ride.
PM turn out
PM mucking out
Bring them back in, brush, pick out their feet
That's just two horses, think about the $$$ it will cost to keep more.
It's a great thing your trying to do but alot of people don't know what they're getting into before they are already in too deep.
