Chickens cope with cold far better than with damp, stale air and draughts at body height, so a winter journey is a balancing act between the two. The birds should travel in a solid crate, pet carrier or purpose-made poultry box that keeps wind off them at the level where they sit, while air still moves through openings above their heads. Seal every vent to 'keep the heat in' and you trap moisture from their breath and droppings, which cools them faster and fouls the air they breathe; leave the crate open to a winter gale and a small hen loses heat all the way. Aim for sheltered, moving air — the travelling version of a good coop.
The crate, bedding and loading
Line the carrier deep with dry straw or shavings so the birds are insulated from a cold vehicle floor and can settle into the bedding rather than slide on it, and check that feet cannot slip through any mesh base. Give hens room to sit and turn but not so much space that they are thrown around; overcrowding overheats and panics them even in winter, while a half-empty crate in a cold car leaves a single bird with no shared warmth. Load them calmly in dim light, ideally after they have fed and drunk, and handle each bird with both wings held gently against her body. A cover — an old blanket or tarp — over the top and windward side of the crate cuts the worst of the draught while the high vents stay open.
During the journey and at stops
Position the crate where it cannot slide, away from direct heater blast and exhaust fumes, and drive as smoothly as the road allows; braking and cornering are weather to a hen. Keep the journey as short as the move permits and be wary of long stops in a cooling vehicle, where birds that were warm while travelling chill standing in a car park. At stops, lift the cover and look rather than guess: birds hunched, fluffed and silent in a huddle are cold; birds panting with wings held away are too hot even in January, usually from an over-sealed crate in a heated car. Offer water at every proper stop — travelling hens dehydrate quietly — and top up spilled or frozen water rather than assuming the drinker survived the bends.
Arrival at the winter coop
Have the destination ready before you unload: a dry coop with deep bedding, ventilation above roost height, no draught slicing across the perches, and water that is not frozen, with feed down as soon as the birds are in. Carry each hen in and set her on the floor rather than tipping crates out, then leave them to reorganise in peace and check again within the hour and at dusk that everyone is eating, drinking and roosting. A bird who stays fluffed, off her feet or apart from the flock after arrival needs warmth, water within reach and a closer eye, and advice if she does not pick up. Listing the journey's checks — who offers water, who inspects the crate at each stop, who does the dusk check — in KinsLe's Care Teams means each job is assigned to a named person and stamped done, instead of everyone assuming someone else looked in on the hens.
