Young pigs moved outdoors face two problems at once: they are small, with little fat cover to burn, and the outdoors is draughty, damp and changeable in a way the barn they came from was not. The shelter has to do the work their bodies cannot yet do — block the wind, shed the rain, and hold a pocket of warm, dry air around a sleeping pig.
The shelter: dry, draught-free and pig-proof
An ark or hut with a low profile holds heat best, because the warm air has less volume to escape into. It needs a solid floor or a raised, dry base — a pig sleeping on cold, damp ground loses heat faster than the air around it can replace it. Face the entrance away from the prevailing wind, and size the sleeping area small enough that the pigs' own body heat warms it, but with room for every pig to lie flat without climbing over the others. Young pigs chew and rootle at everything within reach, so fixings should be smooth, strong and free of anything a snout can work loose.
Bedding does the insulating
Deep straw is the real heating system. Bed the shelter generously enough that the pigs can burrow completely under it — a properly bedded young pig disappears into the straw with just a snout showing, and that buried position is the warmest one available outdoors. Add fresh straw before the bed gets damp or compacted, and clear out wet patches promptly: damp bedding conducts heat away and cools pigs from below even inside a good ark. A pig that comes out in the morning dry and unhurried has slept warm; pigs that emerge stiff and hunched have not.
Heat for the first nights outside
If nights are cold, newly moved pigs benefit from a heat lamp or a heated creep corner inside the shelter for the first week or so, positioned so they can move toward it or away from it — the choice matters as much as the heat itself. Watch how they settle: pigs piled in a heap directly under the lamp are still cold, while pigs spread out across the bed, touching but not stacked, are comfortable. As they grow and the weather settles, withdraw the heat gradually over several nights rather than switching it off on the coldest one.
Read the group every morning and evening
The pigs themselves are the thermometer. Sleeping in a tight, shivering pile, squealing, and reluctance to come out to feed all say cold. Lying apart with legs stretched out on a hot afternoon says something different: young pigs cannot sweat, and on a sunny day they will need shade and a wallow sooner than they ever needed warmth. A pig that stays in the shelter, off its feed and quiet while the others are out, is the one to look at closely — and if it is not itself by the next feed, a farm vet's advice is the next step.
