Hi there!
I have several, (6) and although I'm not an "expert" on the breed, I can help some! Too bad you are not closer, I have a 15 year old grey gelding that needs a home. A young friend of recieved him, and brought him here for short time board. Then she quit her job,and decided she couldn't afford him....so I came into the barn with a Dear Keri letter posted, along with his papers, to the tack room bullitin board. I could auction him, but just can't do that...to many unknowns out there, and he really is a nice boy. Anyway, that said, there are indeed Palomino "colored" arabians...you just have to look for them! They do not have to be stalled, but do need a run in or some sort of shelter from the weather and flies. The size of the stall depends on the size of the arab, most of mine barely reach the 14.2, get over the pony size, and do well in a 10 x 10. However there are some larger arabs and they would require at least a 10x12..if not a 12x12. When I say require, it really means how much time they will spend in the stall, as they do need some room to move around, stretch, and lay down. However, I do have some friends that keep there's in stall much smaller, but these horses are outside quite a bit, and only in when the weather is bad..ie, really hot, buggy, storming hard, wind blowing into the run in...etc.. let me know if you have specific questions and I'll try to answer them..They do for the most part have the most amazing personality, and work ethic!
