A donkey sharing a yard with horses lives beside food that was never mixed with him in mind. Horse rations are built for animals that work harder and burn more, rich in energy a donkey's thrifty system simply stores. Nothing dramatic happens on day one, which is precisely the problem: the extra calories arrive bucket by bucket, disguised as kindness and companionship, and the donkey quietly lays them down as fat.
The signs written on the neck and ribs
Fat on a donkey does not spread the way it does on a horse, so learn where this species parks it. Run a flat hand along the top of the neck: a crest that feels thicker than last month, and especially one that has begun to harden or flop to one side, is stored energy with nowhere else to go. Look for rounded pads over the ribs, behind the shoulder and across the hips, and a belly that swings lower between the front legs. Behaviour tells the same story. A donkey growing reluctant to walk out, shifting weight between front feet on hard ground, or standing camped and sore after time on rich grazing is showing you feet under pressure from weight they were not built to carry.
A one-week separation test
Guessing ends the day you feed everyone apart. For one week, bring the horses in for their buckets and give the donkey his own space with weighed straw and plain fibrous forage, then watch honestly. Does he clear the straw, or does he spend the week waiting at the gate for the horses to finish? Does he leave his own fibre untouched yet appear beside an emptied horse bucket within minutes of turnout? A donkey who barely touches modest forage but materialises wherever richer feed appears has told you exactly where his surplus comes from, and the week's notes give you a true picture of appetite rather than a hopeful one.
Feeding apart for good
Make the separation permanent and boring. Feed the donkey behind a gate or in a pen the horses cannot reach, base his ration on straw and mature, stalky hay, and treat grazing time on lush pasture as a ration in itself — short spells, not all day. Weigh his forage instead of judging by armfuls, and body-condition score him monthly with your hands, not your eyes, because a thick winter coat hides a growing crest from anyone who only looks. Keep treats out of the equation entirely: a donkey needs no bucket to feel included, and a handful of horse mix given daily for companionship undoes a careful ration one handful at a time.
When extra weight stops being cosmetic
In donkeys, surplus fat is a health risk, not a looks issue. Sore feet, a hardening crest and reluctance to move can be early warnings of laminitis and of the dangerous fat-mobilising illness that overweight donkeys are prone to when stressed or off their food, so involve your veterinarian promptly if feet turn sore, the crest changes quickly, or appetite drops. Never crash-diet a donkey who is already unwell; weight comes off this species slowly and under guidance. Back at the yard, put the arrangement into KinsLe's Care Teams: name one person for the morning straw net, another for turning the horses out after their feeds, and let each duty close with its completion time logged, so the separation survives busy weeks and different helpers.
