Best chicken coops for 6 hens (2026)

Short answer: whatever you buy, the inside needs 24 sq ft and the run 60. Check the interior dimensions. This page does not publish a price.

Quick answer: Six hens need a 24 sq ft coop (about 4×6 ft) with a 60 sq ft run, 2 nesting boxes, and about 5 ft of roost bar. Read the interior dimensions before you buy a prefab labeled for 6 hens.

First, the number that disqualifies a listing

Run the calculator: 6 standard birds → 24 sq ft coop, 60 sq ft run, 2 nesting boxes, and about 5 ft of roost at the 10-inch end of Utah's 6–10 inch range. Ignore the bird count on the label and read the interior dimensions. Divide interior square feet by 4. If that result is lower than the headline bird count, the floor is under this site's 4 sq ft planning rate. Penn State's large-chicken indoor minimum is 2 sq ft, which is a different, lower bar.

Three ways to get the floor

1. A prefab that is actually 4×6 or larger

Look for a walk-in whose interior is at least 24 sq ft, with vents. Check: plywood walls (not MDF/particle board, which swell and rot), asphalt or metal roof, actual latch hardware. Ship-flat prefab can arrive with staples where there should be screws.

2. Kit or DIY

A 4×6 coop is 2×4s, plywood, a roof, hardware cloth, hinges, and locks. This page does not publish a material price. The build is the route that lets you set roost height and vent area yourself.

3. Buy the small coop anyway and add a run

If you already own a small coop, keep it as the roost and nest room and attach a run. A 10×6 ft run is 60 sq ft, the 10 sq ft rate for six hens. Twelve square feet inside is the 4×3 ft row above, which is 3 hens at 4 sq ft, not 6. Four hens at that same rate are the 4-hen example.

Then budget the other half of the hobby

The coop is the one-time decision; feed is the repeating one. Six hens eat about 46 lb of layer feed a month — roughly one 50 lb bag — at the quarter-pound rate on the feed cost guide. This page does not publish a coop price, a bedding price, or a payback year.
