We have kept our two horses in a yard about the size of a medium-large house for the last two years. They get 5-6 hours turnout in May - October (depending on the weather) and ridden several times a week (also depending on weather). We are getting a 3rd horse who will be kept with them and I want to know whether we should extend our yard so they have more space. I know its good for them to have extra space but since they'll just trample everything to bare dirt, it seems kinda pointless to give them a little extra space when it'll only be bare dirt. They currently have enough room to trot around easily and can canter for very short stretches.
What do you guys think?
Oh, the sizes of the horse are:
And not sure of the 3rd... but probably about 14.2 or so
