I took a pair of Clydes to winter for friends in the hopes of using them.. a mare and a gelding. I haven't gotten to drive them yet, but… they are both a bit thin and the gelding is quite thin… they have been wormed and teeth floated and I am told the gelding is a hard keeper.. any thoughts on what best to feed him to put some weight on? I am thinking beet flakes mixed with some oats… they are getting free choice, good grass hay plus they share a small bale of 2nd cutting alfalfa (around 50 pound bale) a day.. they seem bright and healthy, just thin… They are supposed to be i their mid teens but I wonder if perhaps they aren't older… I have thought of having a professional who works on horse teeth come and check them out, tho' I hate to go to the expense if they have already been floated and the history of the gelding is that he is a hard keeper… I am 60 miles from a vet or the guy who floats teeth.. they are about 17 or 18 hands tall so I hate to haul them in my trailer as it isn't all that tall, especially for horses this size… any observations or ideas are welcomed. Thanks.
