Elderly horse lost weight during a really cold wet spell a few weeks ago when she was out in heavy rain without a rug as rain not been forecast! I want to get some weight back on her before proper winter but we have really lush looking grass coming through so don't want to tip her into laminitis. Any ideas, should I just start haying (which would mean field companion fatty also getting fatter)or up her hard feed. Not had this problem in previous years as both nags do well on minimum feed
