Breed-aware space math, roost and nest geometry, run fencing, ventilation targets, and a shareable materials takeoff—so your coop fits the birds you actually keep.
Guided flock-to-structure sizing with live schematic previews from your numbers.
Illustrative marketing figures; not App Store metrics.
Enter hen count, production focus, and climate band. Instant indoor floor-area, run-area, and comfort-density figures from seeded husbandry standards, with imperial/metric toggle.
Adult weight bands, temperament tags, cold/heat hardiness, broodiness notes, and per-bird space factors feed the engine as you add, remove, or quantity-change birds on the builder.
Roost bar length and height bands, nest-box count and shelf layout, pop-hole size, door clearances, and minimum continuous ventilation area scaled to flock heat load.
Rectangle, L-run, or tractor footprints yield perimeter, buried apron, cloth height, and netting area—plus framing, sheathing, wire rolls, fasteners, bedding, and insulation with adjustable waste.
Clean top-down coop-plus-run preview with dimension callouts, roost line, nest bank, and pop-hole markers driven by sliders and fields—export plans as PDF or plain text.
Save multiple structure plans locally, duplicate to compare area and materials Charts side by side, pin a Home Screen summary, and open climate-filtered seasonal care boards.
Layer vs dual-purpose focus, hen count, and mixed breeds from dense seed plates.
Indoor floor, outdoor run, roost length, nest banks, pop-holes, and ventilation targets update live.
Framing, hardware cloth, fasteners, bedding, and optional insulation with waste factor.
RoostSpan Coop Kit is a backyard flock-to-structure sizing engine for keepers who are building or expanding a coop the right way the first time. Set hen count, layer vs dual-purpose focus, and climate band, then compose a mixed flock from 45+ seeded breeds. Live readouts translate weight, hardiness, and space factors into indoor floor area, outdoor run, density warnings, roost length, nest banks, pop-holes, and continuous ventilation tied to flock heat load.
Shape presets drive run footprint, buried apron, hardware-cloth height, and netting; a materials takeoff lists framing, wire cloth, fasteners, bedding, and optional insulation with waste factor. Top-down schematics update from your numbers—not a drag sandbox—and named plans stay on-device with side-by-side Charts and a Home Screen widget for the active space summary.
