System exploded
Site → shell → care → run
Build / decision sequence
Start with the system: flock conditions, site, coop direction, interior routine and run. Only then take the unresolved structural, permit and electrical questions to the appropriate local review.
See the reference boardOriginal information diagram
Match flock and routine to a coop direction.
Map site, interior, run and daily access together.
Resolve local structural, service and permit requirements before construction.
System sequence
Read the configuration as a decision prompt. The next table and checks keep the conditions explicit.
Site → shell → care → run
Choose → test → confirm
Observe first; do not assume

Material context
Editorial reference only — confirm final selections for the flock, site and routine.
Compare before deciding
Build checkpoints. Use it to prepare questions for the route that fits your flock, yard and routine.
| Checkpoint | Answer before moving on | Do not assume |
|---|---|---|
| Site | Drainage, exposure, access and local limits | A generic layout fits every yard |
| Format | Compact, walk-in, moveable or converted | One design solves every routine |
| System | Air, roost, nest, run and cleaning relationship | Final structure or services from a guide |
| Review | Who verifies local conditions | Online advice replaces local authority |
Daily use
These tasks reveal whether the option stays workable once it becomes ordinary care.
Start with the repeated work: access, eggs, water, bedding and inspection.
Connect site, interior, run and weather before materials are selected.
Take structural, service and permit questions to the appropriate review.
Options with conditions
Each direction earns its place only when the stated condition holds up in the real yard and routine.
Regret check
These are decision warnings, not predicted outcomes or construction advice.
Decision context
These modules make costs, climate and ownership questions explicit without inventing a universal price, local recommendation or anonymous review.
Cost context
This is a scope map for local comparison, not a total-price promise.
Drainage, access and local constraints should be known before the system is costed.
Ask locally: What site question could invalidate the first material list?Coop, interior, run and care route affect one another.
Ask locally: Which system boundary is missing from the current budget?Late changes often occur when the routine or local review was excluded.
Ask locally: Which decision is cheap to test now but expensive to reverse later?Climate context
Climate context sets review questions; it does not provide an engineering, heating or permitting answer.
Drainage, access and the lower edge of the system.
Confirm: Observe the actual yard before deciding on a final approach.Sun, wind, weather and the normal human route.
Confirm: Carry the condition into a local material and design review.Whether water, cleaning and inspection remain workable.
Confirm: Keep site-specific structural and service decisions outside this guide.Ownership test
Run this sequence before spending: it turns the abstract build order into ordinary care decisions.
Can you name the flock, site and full daily route?
Decision: Do not price a system until its operating condition is clear.Have interior and run relationships been tested on the actual site?
Decision: Resolve the layout conflict before committing to work.Which item still needs local structural, service or permit confirmation?
Decision: Hand off that item instead of extending this guide beyond its boundary.Reality check
Have the coop and run been planned as one daily-use system?
Which local decision is still unresolved?
Does the design leave human access visible, not assumed?
