What's Inside the Plans
Sample sheets from the complete 40-page plan book — dimensioned drawings, cut tables and build references drawn at print quality. The previews below are watermarked; the book is not. Everything published on this page stays free.

Floor Framing
7 joists at 16" on centre running the short direction, rim doubled on all four sides, 42" clear span — comfortably inside the published span tables, so no intermediate support is needed. True 16" spacing means plywood seams land on framing.
The 18 Assembly Steps
Every step, with the cut list it needs. The summaries here are the short version — the complete 40-page book carries the full written instruction for each one, plus the stop-and-measure checkpoints.
Every cut length below is computed from the same geometry that draws the PDF, so the numbers on this page and the numbers in the plan set cannot disagree.
2
Base supports
The base ring ties the four posts into a rigid square at grade. Use the 4-inch screws here — this joint carries the racking load for the life of the coop.
| Part | Qty | Length | Stock | Note |
|---|---|---|---|---|
| Base support A (front/back) | 2 | 41" | 4x4 | |
| Base support B (sides) | 2 | 89" | 4x4 | |
| Base blocking | 8 | 20-1/2" | 2x4 |
3
Floor joists
Joists sit 14" above grade on 16" centres, running the short direction across 42" in 2x6, with the rim doubled on all four sides.
| Part | Qty | Length | Stock | Note |
|---|---|---|---|---|
| Rim joist (long sides) | 4 | 96" | 2x6 | doubled |
| Floor joist | 7 | 42" | 2x6 | 16" OC, last bay short |

Floor deck
Deck the floor in 3/4" plywood, notched 3-1/2" square at each corner so it drops cleanly around the posts.
| Part | Qty | Length | Stock | Note |
|---|---|---|---|---|
| Floor panel | 1 | 48" x 96" | 3/4" plywood | notch corners |
5
Wall framing — the method
Every wall is framed FLAT ON THE DECK and then stood up. That is the whole trick: you are working on a level surface, gravity holds the parts where you put them, and you can push the frame square before a single screw goes in.
5a
Front wall (low eave)
The low side. It carries the door and most of the glazing.
| Part | Qty | Length | Stock | Note |
|---|---|---|---|---|
| A Bottom plate | 1 | 89" | 2x4 | sits flat on the deck — cut out at the doors AFTER standing |
| B Top plate | 1 | 89" | 2x4 | first plate over the studs |
| C Cap plate (upper top plate) | 1 | 86" | 2x4 | laps the corner — long walls SHORT both ends, end walls LONG both ends |
| D King stud (full height, beside the opening) | 6 | 48" | 2x4 | full height, outside the jack |
| E Jack stud (carries the header) | 2 | 44-1/2" | 2x4 | carries the header, sits ON the bottom plate |
| F Jack stud (carries the header) | 4 | 41-1/2" | 2x4 | carries the header, sits ON the bottom plate |
| G Header | 2 | 33" | 2x4 | two pieces + a 1/2in plywood spacer = 3-1/2in thick, flush both faces |
| H Header | 4 | 21" | 2x4 | two pieces + a 1/2in plywood spacer = 3-1/2in thick, flush both faces |
| I Rough sill | 2 | 21" | 2x4 | rough sill under the window |
| J Cripple under the sill | 6 | 17" | 2x4 | between bottom plate and rough sill |
| K Cripple over the header | 6 | 3" | 2x4 | between header and top plate |
5b
Back wall (high eave)
The HIGH side — its studs are longer than the front wall's by the full rise of the roof.
| Part | Qty | Length | Stock | Note |
|---|---|---|---|---|
| A Bottom plate | 1 | 89" | 2x4 | sits flat on the deck — cut out at the doors AFTER standing |
| B Top plate | 1 | 89" | 2x4 | first plate over the studs |

| E King stud (full height, beside the opening) | 2 | 58-1/4" | 2x4 | full height, outside the jack |

| J Cripple over the header | 3 | 27-1/4" | 2x4 | between header and top plate |
5c
Left end wall (run end)
The run attaches to this wall and the pop door passes through it. Seen from outside, the roof runs DOWNHILL left to right.
| Part | Qty | Length | Stock | Note |
|---|---|---|---|---|
| A Bottom plate | 1 | 41" | 2x4 | sits flat on the deck — cut out at the doors AFTER standing |

Shed rafters
A single-slope shed roof at 3:12 — 12" of fall across the 48" width, which is the minimum pitch exposed-fastener corrugated metal will shed reliably.

| Shed rafter | 5 | 55-1/2" | 2x6 | birdsmouth both ends, 6" tail |

7
Roof deck and metal
3/4" plywood over the rafters, then corrugated metal sheets. Metal over shingles because it sheds snow, lasts decades and never needs a tear-off.
| Part | Qty | Length | Stock | Note |
|---|---|---|---|---|
| Roof deck panel | 2 | 4' x 8' sheet | 3/4" plywood | lay the 8-ft dimension UP the slope; seams land on a rafter |

Siding
Lap siding in 9-foot courses, starting from a level chalk line at the bottom and working up.

8b
Doors, hatches and lids
Every opening you framed in step 5 now gets something to close it. Cut each slab a quarter inch smaller than its rough opening on all four sides — 3/4in plywood swells in the wet and a door cut to the exact opening size will bind by November.
| Part | Qty | Length | Stock | Note |
|---|---|---|---|---|
| Access panel slab | 1 | 29-1/2" x 45-1/2" | 3/4" plywood | 3 hinges, opens out |

| Nest bank frame | 4 | 30-1/4" | 2x4 |
10
Pop door and ramp
The pop-door slab was already cut in step 8b to fit the opening you framed in step 5c — do not cut another one.
| Part | Qty | Length | Stock | Note |
|---|---|---|---|---|
| Ramp | 1 | 47-1/2" x 10" | 3/4" plywood | trim to your measured drop |
| Ramp cleat | 11 | 10" | 1x2 | every 4in, so a hen has grip |

The step that decides whether you still have a flock in two years. Quarter-inch hardware cloth over every opening, screwed through fender washers rather than only stapled.
| Part | Qty | Length | Stock | Note |

Roosts and droppings board
6 birds NEED 60 inches of perch at 10 inches each. Why 10 and not the 6 you have read everywhere.

Frequently Asked Questions
Are these 4x8 chicken coop plans really free?
The 6-page preview PDF is a free download with no email required, and everything published on this page stays free — every dimension, the spec table, the complete material list and all 18 assembly steps with their cut tables. The complete 40-page plan book — every wall on its own sheet with its own cut table, a board-by-board cut plan and a material buy list — is $4.99 on Etsy.
How many chickens fit in the 4x8 chicken coop?
4-6 hens. At 23 sq ft of floor, 4 birds get about 6 sq ft each, with 32 sq ft of screened run on top of that. The top of the range (6) assumes the birds spend their days outside rather than shut in.
What's in the full 40-page plan book?
Everything on this page — dimensioned plan and elevation drawings, the complete bill of materials (30 line items) and all 18 assembly steps with per-step cut tables — plus what a web page can't carry: the full written instruction for every step rather than the summary shown here, every wall framed on its own sheet, a board-by-board cut plan, a buy list you can hand to the lumber yard, and stop-and-measure checkpoints at each stage. The free 6-page preview PDF shows the design overview and main dimensions. On-page specs are computed from the same geometry that draws the PDFs, so the numbers can never disagree.
