Why Runs Turn: Moisture Plus Spilled Feed
A chicken run rarely smells because of the hens. It smells because droppings land on damp ground and stay there, fermenting instead of drying, and rats arrive because spilled and leftover feed tells them the address is worth visiting. Every useful daily check attacks one of those two causes, which is why the routine below is short: you are not deep-cleaning daily, you are refusing to let moisture and food accumulate in the first place.
The Morning Walk-Through
Open up and pause at the gate for a deliberate sniff — your nose catches a sour, ammonia edge days before the run looks dirty. Look for the wet patches that cause it: the drip line under the drinker, the hollow where hens queue at the pop-hole, the shaded corner that never dries. Fork those spots over to expose dry material, sprinkle fresh bedding or woodchip where the surface stays damp, and move the drinker if its puddle is the permanent problem. Check droppings under the perches too; a sudden change in colour or consistency is often your earliest hint that a hen is unwell, and it costs nothing to glance while you are there.
Feed Discipline That Starves Rats Out
Rats do not need your feed store if your feeding routine serves them in the run. Feed measured amounts in pans, a hanging feeder or a treadle feeder the hens operate themselves, rather than scattering grain across the ground where half of it vanishes into the litter. Lift or close away anything unfinished before dusk, because rats feed at night and hens do not. Store the feed itself in a sealed metal bin with a tight lid — plastic is a chewing exercise, not a barrier — and sweep the store area so the bin is not ringed with spilled rations. Water deserves the same discipline: a drinker rats can reach at night is another reason to stay.
Ground and Bedding Management
Dry litter is doing quiet work for you: it absorbs droppings, lets hens dust-bathe and scratch, and denies smell a foothold. Keep it topped up little and often rather than in one deep annual layer, and rake it so droppings break down instead of capping the surface. If your run is fixed rather than movable, accept that the ground needs resting or renewing — a thick fresh layer of woodchip over tired earth transforms most runs. Watch drainage after rain: a run that puddles will smell within days, so dig a shallow channel or raise the wettest corner before the next storm, not after.
Catching the First Rat Signs
Walk the run's edges weekly looking for what a rat leaves before it shows itself: a smooth new burrow hole near the fence line, droppings along a wall, gnaw marks on timber at ground level, or a greasy smear where bodies squeeze through a gap. Act the day you find one — clear cover and harbourage near the run, seal the gap, tighten feed discipline further, and set about removal promptly, because a single pair becomes a colony on a timetable you will not enjoy. If signs keep appearing despite tight feeding, or you find rats inside the coop itself, bring in a professional pest controller rather than escalating home efforts. These small rounds are easy to keep consistent with KinsLe Care Teams, where the morning sniff-and-fork check can be assigned to whoever feeds the hens and marked done with a timestamp.
