Horses only have four legs... so if you meant to ask "why do horses have four legs" then the answer would be that four legs fit the horses needs the most, for example six legs would make it hard to turn and would make the horse too long. But in the same way two legs wouldn't be enough because the horse would have to stand on its hind legs and since it wasn't made for two legs the horse wouldn't be able to stand up and would fall over.
Horses have two knees, one on each foreleg. The equivalent joint in the hindlegs is called the hock.
It's four legs support the substantial weight of the horse's body.
If all were horses there would be 4 x 61 ie 244 legs. There is a shortfall of 50 legs ie 25 less four-legged creatures, so there are 36 horses and 25 chickens, giving 144 + 50 legs
Horses are quadrupeds, so they have 4 legs.
