Due to our weather, I don't usually clip very early, not before mid-April at the earliest, and usually later than that. But, last year, my newest little stallion was so woolie and he was just throwing himself at the fence posts and anything else that wouldn't move, he was so itchy with the warming weather, so I did clip him (he also wears a blanket in cold weather, so had his blanket should he need it). I try not to clip too early, but sometimes, I do end up head and neck clipping them if we have on and off warm weather, as they get so miserable in their thick winter coats.
