A hawk or buzzard hunting your range is doing simple mathematics: it needs a hen in the open, far enough from cover that the stoop lands before the hen reaches safety. Hens that range across a bare paddock with the only shelter at the coop are gambling every hour of the day. You cannot remove birds of prey — they are protected wildlife and part of the countryside — but you can change the arithmetic until your flock is more trouble than the voles in the hedge. The method is cover, placed the way hens actually move, backed by habits that stop the flock bunching predictably in the open.
Scatter cover the way hens actually range
Watch where the flock spends the day: hens work outward from the coop in loose circuits, following scratching ground, dust-bathing spots and shade. Put something solid at intervals across that circuit — a low shrub, a pallet raised on blocks, an old stock trailer, a sheet of tin on posts — anywhere a hen can dive under within a few strides. A hen that makes it under cover has won; hawks rarely pursue on foot into a tangle. Overhead lines help too: wires or ropes strung between posts over the most-used area, and netting over a smaller core range near the coop, break up the clean dive line a stooping bird needs. Rotate which part of a larger field the hens use if you can, so worn bare patches near the coop do not force the whole flock to feed exposed in one predictable place.
Feed, water and timing habits that lower the risk
Feeders and drinkers placed in the open anchor hens in the danger zone for long, head-down minutes. Set them beside or under cover instead. Scatter feeding into long grass or under shrubs keeps the flock dispersed and heads-up rather than crowded in a ring. Attacks cluster at certain hours — many raptors hunt hard in the first hours of light and again towards evening — so on a smallholding with a known problem, letting the hens out a little later and shutting them in before dusk trims the riskiest edges of the day. A good cockerel earns his feed here: he watches the sky while hens feed, gives the alarm call that sends the flock running for cover, and his presence alone makes some hawks choose another field.
Deterrents: useful, briefly
Scare devices — a reflective tape line, a silhouette kite, a plastic owl — work until the local hawk learns they never move, never strike and never matter, which takes days rather than weeks. If you use them, move them every couple of days and treat them as a supplement to cover, never the strategy itself. What does not work is confining a flock that has known range to a tiny pen at the first loss and calling it protection: the hens lose the life the ranging was for, and the real fix, cover across the ground they use, is usually a weekend's work with materials already on the farm.
Lock-up at dusk is a duty, not a habit
More hens are taken at the edges of the day than in all the dramatic midday stoops, and the flock most at risk is the one still out because shutting the coop slipped. Fix the lock-up to the light rather than the clock, and put a name against it daily — including the evenings you are away and someone else is doing the yard. On KinsLe, Care Teams carries the dusk lock-up as an assigned duty on the flock's care list, so the person covering that evening sees it as their job and the completed shut-in is timestamped, not assumed.
