A Leghorn Notices Everything After Dark
A Leghorn chicken is a light, quick, watchful bird, and this Mediterranean layer settles less deeply than heavier dual-purpose breeds even on a good night. Genuine restlessness, though, with hens shuffling along the perch, flapping down and back up, calling and re-arranging for hours, has a cause inside or just outside the coop. Leghorns will tell you the coop is wrong long before egg numbers do, so treat a noisy night as inspection instructions.
Mites That Only Come Out at Night
A Leghorn flock restless mainly after dark, with hens reluctant to go onto the perches at dusk or pale combs developing over weeks, should be checked for red mite. These parasites hide in perch ends, nest-box joints and cracks by day and climb onto the birds to feed at night, so the flock's misery peaks exactly when you cannot see it. Take a torch in after dark and look at the perch and the birds' legs, or wipe a white tissue along the underside of the perch and look for smears. Treating the coop's cracks and fittings matters as much as treating the birds, since most of the population lives in the woodwork.
Light Leaks and Things Around the Walls
A Leghorn wakes early by temperament, and light leaking through a coop gap from a yard lamp, a neighbour's security light or passing vehicles can convince the flock that dawn has arrived at two in the morning, complete with laying calls and squabbles over nest boxes. Block stray light where it hits the roosts, while keeping proper ventilation gaps open, because a sealed, stuffy coop creates a different restlessness of panting and wings held away from bodies. Scratching, scuffling or a predator testing the run will also keep this breed rigid and vocal on the perch, and tracks, dug soil or pulled feathers in the morning confirm the night was genuinely interrupted.
Perch Politics and Crowding
A Leghorn flock sorts its sleeping order nightly, and too little perch space, perches at competing heights or a new hen added recently turns bedtime into a long negotiation of shuffling, pecking and birds being pushed off. Provide enough roost length that every hen can sit without touching a neighbour if she chooses, at one even height, and expect a few disturbed nights after any flock change while the order resets. A hen who is repeatedly found sleeping in a nest box may be avoiding bullying on the perch rather than choosing comfort.
Heat, Air and a Coop That Smells Wrong
A Leghorn in an over-warm, poorly ventilated coop pants, holds her wings out and keeps repositioning, and ammonia building up from droppings under the perches irritates airways enough to keep a whole flock wakeful and sneezy. You should not be able to smell the coop strongly at bird height when you duck in at night. Clear the worst droppings, refresh bedding and improve high-level ventilation that lets moist air out without blowing directly across the roosting hens.
When a Restless Hen Needs More Than Coop Fixes
A Leghorn who is restless alongside laboured breathing, a swollen abdomen, standing in a penguin-like posture, going off lay with a drop in condition or being found weak under the perch in the morning needs a veterinarian, ideally one who treats poultry, rather than another coop adjustment. Note which hen and what you saw, because flock-level descriptions help a vet far less than one bird's clear history. Recording the nightly coop checks and any bird singled out, alongside the closing-up tasks in KinsLe Care Teams, gives the flock's carers one shared picture of whether the restlessness is mites, light or a hen who needs help.
