## What's Included in This Offset Chicken Coop Plan

The Oakhurst breaks the straight line most coop-and-run builds follow. The cream board-and-batten coop with black trim stands back on the left, and the black-framed walk-in run steps 4 ft forward on the right, so the building reads as two staggered parts under one long shingled roof whose edges step in and out with them. The cedar coop door and its steps sit in the sheltered inside corner, the nest box hangs on the coop's left end for collecting eggs from outside, and the hens walk down a ramp from the pop door straight into the run.

- 12' x 10' walk-in coop with 107 sq ft of floor inside, 7' 2-1/2" high at the front wall rising to 9' 6-3/4" at the back wall, on short posts with the floor 2' 1-1/2" up
- Attached 14' x 12' walk-in run with about 153 sq ft of ground, all under the roof, with 6' 8" clear under the door header and a 31-1/2" x 75-3/4" run door
- Cedar Z-brace coop door 32" x 72-1/2", two steps up in the inside corner
- Outside nest box on the left end wall with 5 nests at chest height and a shingled lid for collecting eggs without going in
- Three 110" roost bars with 330" of perch over a removable dropping board
- Guillotine pop door in the right end wall with a cleated ramp into the run
- Four six-lite casement windows (two in front, two high at the back), louvered vents in both end walls and screened eaves
- Z-shaped shed roof at 3/12 with 7 coop rafters and 8 run rafters, ice-and-water membrane, architectural asphalt shingles and two front gutters
- 1/2" hardware cloth on the run with a 24" apron
- Estimated material cost of about $6,500 to $8,400 (prices vary by region and season)

## Large Walk-In Chicken Coop with Attached Run for 20 to 25 Hens

The coop gives 4.3 to 5.4 sq ft per hen and the covered run 6.1 to 7.7 sq ft per hen, so this large chicken coop houses 20 to 25 chickens; for 25 hens add some supervised free-range time. The 5 nests follow the rule of one nest for every 5 hens, and the three roosts give about 13" of perch per hen at 25.

## File Format, Paper Size and Measurements

The plan is a 71-page PDF on US Letter paper. All dimensions are in feet and inches for standard US lumber, with the main sizes also listed in millimeters. Drawings are not to scale, so always use the written dimensions.

## Who This Walk-In Chicken Coop Plan Is For

This is an intermediate build for DIY builders who are comfortable with a circular saw, a jigsaw, a drill/driver, an impact driver and basic framing. Two people can build it in about 10 to 12 weekend days, plus painting. Spring is the busiest building season, so fall and winter are a good time to price lumber and prepare the site before new chicks arrive. It also makes a practical gift for a backyard chicken keeper.

## Frequently Asked Questions

### Why is the chicken run offset from the coop?

The offset gives the coop door a sheltered corner beside the run and breaks up the long side of the building. Inside nothing changes: the hens walk down the ramp straight into the run.

### Can I line the run up with the coop instead?

Yes. Move the run posts 48" back and set the run beams at the coop's plate heights; the run rafters then match the coop rafters and the inner barges are not needed.

### Is a 3/12 shed roof steep enough for shingles?

Yes. 3/12 is above the 2/12 minimum of most shingle makers, provided the whole deck gets ice-and-water membrane or a double layer of underlayment, as shown in the plan.

### Do I need a building permit for this chicken coop?

It depends on your town. The coop floor is 120 sq ft, the roof about 391 sq ft and the high edge about 12' 8-5/16", so check your local rules before you build.
