An adult Khaki Campbell needs about four square feet of house floor and ten to fifteen square feet of secure run per bird, and it will happily use every additional yard of ranging ground it is given. The breed was developed as a laying duck, and a laying Khaki Campbell is an active, purposeful bird that spends its day walking, dabbling, and hunting insects rather than sitting still. Plan space for a small flock rather than a pair where possible — ducks are social, settle better in a group, and forage more confidently with company — and build the house and run around the group's combined footprint.
Housing a laying flock at ground level
Khaki Campbells sleep and lay at floor level, so the house is a dry, low building with deep litter and quiet corners where a duck can make a shallow nest scrape and lay in the early morning. Ventilation should sit high in the walls to carry off moisture from bedding and breathing without chilling the birds, and the floor must stay dry, because ducks brought in wet from the run will soak litter quickly. Collecting eggs is part of the housing design: an accessible door and a layout you can reach into without disturbing the whole flock make the daily collection quick. The house has to fasten securely every night, since a laying flock shut in one building is a concentrated target for any predator that finds a gap.
Run, range, and forage quality
The secure run gives the flock its daytime safety, and ten to fifteen square feet per bird keeps the ground from becoming a bare, fouled patch within a season. A roof or net over at least part of the run adds shade, keeps the busiest area drier, and blocks attacks from above. Beyond the run, Khaki Campbells shine as ranging birds: on a garden, orchard, or small field they convert insects, slugs, and weeds into eggs with remarkable efficiency. Fence the ranging area, provide patches of shade and a shallow bathing tub, and move the flock to fresh ground when the old patch is picked clean. Avoid letting ducks range where standing water collects and stagnates, since fouled water is a common route to illness in ducks.
Water placement and mud control
Every duck setup is partly a drainage problem. Khaki Campbells need water deep enough to submerge their heads for eye and nostril health, and they will drill and dabble at any wet edge until it becomes mud. Set bathing water on gravel, slabs, or a drained apron, position drinkers where spillage runs away from the house door, and rest or resurface the gateway area of the run before it becomes a quagmire. In freezing weather, carry out fresh water as ice forms; ducks still need to bathe their heads on cold days even when a full splash is out of the question.
Routines that keep laying birds settled
Laying ducks thrive on predictability: out at the same time, eggs collected on the same rounds, shut in at dusk without a chase. A flock that is stressed by irregular handling or repeated night-time disturbance lays less reliably, so the routine itself is part of the housing plan. Sharing that routine in writing means a neighbor or family member can run it identically while you are away. KinsLe Family Sharing puts your Khaki Campbells' letting-out, egg-round, and lock-up times on a shared profile, so the flock's settled routine continues unchanged whoever is covering for you.
