Coops for five chickens, the flock size nothing is built for

Five is an oddly specific number to search for, and people search for it because it is what they ended up with — four ordered plus one free chick, or six ordered and one lost. It is also the last flock size with a genuinely useful property, and nobody mentions it.

Five is the last flock size that needs one nest box

University of Maryland Extension publishes one nest box per four to five birds. Five is therefore the top of the single-box bracket: at six you are into two boxes, and two boxes changes which coops are candidates and how much interior wall you need.

This is worth knowing because nest boxes are the one coop feature that is genuinely easy to add later, and the one most often over-bought. Hens do not distribute themselves evenly across available boxes. They pick one, decide it is the correct one, and queue. A coop advertising four boxes for six birds is advertising three boxes of storage.

What the coops give five birds

The column headed “measure” is doing most of the work in that table, and it is the reason the ranking is not as clean as it looks. An interior floor area and an external footprint are not the same quantity. The Eglu Cube’s 7.79 square feet is floor you can actually stand a bird on. The OverEZ Medium’s 18.32 is the outside of the building including the nest box bump-out, and the maker publishes no interior figure at all.

OverEZ Medium — the one you can walk into

Stated for ten chickens, which does not survive its own numbers — 18.32 square feet of exterior at ten birds is 1.83 each. At five birds it is 3.66, and that is the only figure on this page with real margin in it. You get a 17 by 38 inch man door, three lockable nest boxes, two roosts, a screened window that opens, and two vents at each gable end.

The honest downside: no published interior floor area, no published roost length and no published weight, so the two figures that decide a capacity claim are both missing. The ten-bird claim is not defensible on anything published. It is wood, so it wants annual attention. And it is comfortably the most expensive way to house five birds covered here.

Producer’s Pride Sentinel — the six-bird farm-store option

Stated for up to six chickens with three large nest boxes, a steel frame and an 11.70 square foot published external footprint. At five birds that is 2.34 square feet each of external footprint. Three nest boxes covers twelve to fifteen birds at the published ratio, so boxes are not the constraint.

The honest downside: the published footprint includes the run underneath, so the henhouse floor is a fraction of it and the maker publishes neither that fraction nor the roost length. For five birds you need 30 to 50 inches of bar and there is no way to check whether it is there. At 170 pounds of flat pack, this is also not a coop you reposition after discovering it is tight.

Omlet Eglu Cube — the checkable one, and the tightest

The only coop here that publishes what a buyer actually needs: 34 by 33 inches of interior, 7.79 square feet, integrated roosting bars and nest box, a slide-out droppings tray. At five birds that is 1.56 square feet each.

The honest downside: 1.56 is about half the published minimum. Omlet designs around a permanently attached, permanently open run, and under that assumption five birds in a Cube is defensible — the coop is a place to sleep. Under confinement it is not, and a week of deep snow is confinement whether you planned it or not. No published insulation value or temperature rating either.

What we would actually do at five birds

Buy for six. Not because five birds need six birds’ worth of space — they need 15 to 20 square feet and a six-bird coop rarely provides even that — but because the market prices and stocks four-bird and six-bird coops, and at five you are paying the six-bird price regardless. Taking the larger option costs nothing extra and gives you the headroom for the bird you will inevitably add.

Then spend the attention on the run rather than the coop. Fifty square feet is the published figure and it is a five-by-ten structure. Under-building the run is what produces the feather picking and bullying that gets blamed on temperament, and it is far cheaper to fix in advance than to diagnose later. If you are choosing between a bigger coop and a bigger run at this flock size, choose the run.

Three extension services, three different numbers

It is worth knowing that the published space guidance is a range across sources rather than a single agreed figure, because five birds sits right where that range starts to matter for what you buy.

The spread indoors is 12.5 to 20 square feet for the same five birds — a difference of about 60 percent between the most and least generous published figure. Outdoors the spread is wider still, from 20 to 50 square feet.

Our position is to plan to the top of the range rather than the bottom, and the reasoning is asymmetric risk rather than caution for its own sake. Overbuilding costs you money once. Underbuilding costs you feather picking, bullying and eventually egg eating, none of which is easy to reverse once it starts. If a coop clears 20 square feet for five birds you never have to think about it again; if it clears 12.5 you have bought into the most optimistic published figure and left yourself nothing.
