Introduce over the fence first, then in a large space with an even-tempered companion, remove hind shoes if possible, and supervise. Rushing a new horse straight into a tight group risks kicks and injury.
Quarantine first
Keep a new horse separate for a couple of weeks to be sure it is healthy and to avoid spreading disease. This also lets it settle into the new yard’s routine before facing the social challenge of the herd.
Introduce over the fence
Let the newcomer meet the herd over a safe, sturdy fence so they can sniff, squeal and sort out first impressions without being able to hurt each other. Give this several days until the fuss dies down.
Pair with a friend
Turn the new horse out first with one calm, even-tempered member of the herd in a large space. A single steady companion is far easier than the whole group, and the pair can bond before the newcomer meets the others.
Reduce the risk
Introduce in the biggest field available so horses can move away rather than being cornered, remove hind shoes where practical to lessen kick damage, and provide plenty of forage in spread-out piles so there is no need to fight over food. Have a headcollar and lead rope ready in case you need to catch a horse quickly.
Supervise and be patient
Watch the first full turnout closely, expecting some chasing and posturing as the pecking order settles. Step in only if it turns dangerous. Given space, time and enough forage, most herds accept a newcomer within a week or two.
