Sizing a coop for four hens the right way

Four hens is the sweet spot for a lot of first flocks. You get a steady supply of eggs without a big footprint. The catch is that many coops sold for "4 to 6 chickens" are really built for two or three. Here is how to check.

The numbers for four birds

• Coop floor, about 16 square feet for four standard hens (4 per bird). A 4 by 4 foot footprint is the minimum.
• Run, about 40 square feet, such as 5 by 8 feet. More is better if they are confined all day.
• Roost, about 3 to 4 feet of bar, roughly 2 inches wide, so all four can sit side by side.
• Nest boxes, one is enough, but two cuts down on squabbles and broken eggs.

If your four are bantams, you can shrink the coop to around 8 square feet. For more detail on this exact flock size, see what size coop you need for 4 chickens.

What separates a good four-hen coop from a bad one

At this size, the common failure is a coop built like a toy. Look at the wall thickness and the hinges. Thin panels warp after one wet season, and small hinges pull out of soft wood. A pull-out droppings tray is worth a lot, because small coops get dirty fast. Check that the nest box sits lower than the roost and has an outside lid so you can collect eggs without crawling in. Also look at the pop door. If it is so small that a heavier hen has to squeeze through, she will not want to use it.

Upgrades that make a small coop safe

Small coops often use chicken wire on the run. Cover it with 1/2 inch hardware cloth, at least on the bottom few feet and anywhere a hand could reach in. Lay a skirt of wire 12 to 24 inches out from the base and pin it down, so digging animals give up. Add a second latch or a carabiner to every door. For air, put the vents up high, above the roost, so the birds are not sitting in a draft at night.

Price ranges and build versus buy

Prefab coops marketed for four birds often sit somewhere around $150 to $600, and the cheaper end usually needs upgrades before it is safe. A sturdier kit or a small custom build can cost more but last much longer. Building is very doable at this size, and a 4 by 4 coop is a good first project. The coop planner can draw one for you, and the roost length calculator will confirm your bar length.

Common questions about coops for 4 chickens

Can four chickens live in a 3 by 3 foot coop?

Only if they are bantams or have a large run they can use from dawn to dusk. For standard hens, 9 square feet is tight and tends to lead to pecking.

How big should the run be for four hens?

Aim for at least 40 square feet. If they never free-range, giving them more room cuts boredom and keeps the ground from turning to mud.

Can I add more chickens later?

Not without more room. If you think you will want six birds, buy or build for six now. It costs less than replacing a coop.
