Winterizing a chicken coop

Do this in October, before the first hard night. It is one afternoon, and it is the difference between a winter you barely think about and a winter of thawing waterers in the dark.

The coop

1. Strip and clean it out. Full clear-out, scrub, dry completely. Going into winter on clean bedding is worth a lot, because you will be topping up rather than stripping out for months.
2. Inspect for holes and cracks. MSU Extension recommends exactly this: sealing them prevents cold drafts and keeps rodents out over winter. Do it on a windy day with your hand at roost height.
3. Check the roof. A leak you tolerate in September is a wet-litter and frostbite problem in January.
4. Check and clear the vents. They stay open all winter. Add a baffle or overhang if rain gets in.
5. Check the roosts. Wooden 2x4 or 2x2, flat side up. Replace any metal or plastic perch — those hold cold against feet.
6. Lay deep bedding. 6-12 inches of dry material, per University of Minnesota Extension.
7. Fit or clean the droppings board. You will be scraping it daily for months; make it easy.

The run

• Add a wind break on the prevailing-wind side. A tarp or boards. Birds use a sheltered run; they will not stand in the wind.
• Cover part of it if you can, so there is dry ground when there is snow.
• Top up with wood chip to manage mud. Winter runs turn to mud and mud is the start of foot problems.
• Check the mesh and the apron. Predators get hungrier and bolder in winter, and frozen ground is easier to dig under at the thaw.
• Clear anything that will collapse under snow — sagging netting, a flat cover that will pool.

The water

1. Drain and store any hose-fed system before the first freeze, or it will split.
2. Get the heated waterer out and test it now, not on the first frosty morning.
3. Add a thermostat outlet so it is not drawing power through a mild October.
4. Inspect the cord end to end for rodent damage.
5. Decide where it goes, ideally out of the coop, on a tray if it must be inside.

The electrics

• Outdoor-rated cable only, on a GFCI-protected outlet.
• Connections off the ground, out of the bedding, in a dry spot.
• Nothing run through a window on a domestic extension lead.
• Everything checked for rodent damage before it is plugged in. Full safety detail.

The flock

• Expect feed consumption to rise. Extension guidance notes intake increases in cold weather. Buy accordingly and keep feed continuously available.
• Expect laying to drop. Shorter days and the autumn moult both reduce it, in every breed. That is normal.
• Check feet, combs and vents before winter starts, so you know what normal looks like.
• Deal with mites now. A mite problem in an unventilated winter coop is much harder to resolve than one in September.
• Make sure the feed store is rodent-proof. Rodents move indoors in autumn, and the feed bin is where they are going.

The autumn shopping list

Bedding, a heated waterer, the thermostat outlet that cuts its running cost, and the ammonia binder for deep litter.

RentACoop Premium Hemp Bedding, 300L

RentACoop

8.0/10★★★★☆Assessed on specs and owner reports

300 liters of hemp hurd per 30 lb bale. Hemp costs more than pine up front but absorbs more per liter and throws far less dust — which is the thing that actually damages chicken lungs.

Published specifications

Material	Hemp hurd
Volume	300 L
Weight	30 lb
Intended use	Chickens, rabbits, horses

Specifications per Manufacturer figures as published on the Amazon product listing, as published at the date above.

What it does well

• Volume and weight both published, so the real cost per liter is comparable
• Markedly less dust than pine — the single biggest respiratory factor in a closed coop
• Absorbs more liquid per liter than shavings, so the litter stays drier between changes
• Composts readily

Where it falls short

• Costs several times what an equivalent volume of pine does
• Finer particles can sift through widely-spaced slatted floors
• Not stocked in most feed stores, so you are ordering it

Farm Innovators HB-60P Heated Poultry Waterer, 2 Gallon 60W

Farm Innovators

7.2/10★★★◐☆Assessed on specs and owner reports

Two gallons with a 60-watt thermostatically-controlled element built in. Published wattage, published capacity, and the heater is integrated rather than bolted on — the fewest failure points of any heated option.

Published specifications

Capacity	2 gallon
Heater	60 W integrated
Control	Thermostatically controlled
Type	Heated drinker

Specifications per Manufacturer figures as published on the Amazon product listing, as published at the date above.

What it does well

• 60 W is published, so you can work out the running cost rather than guess
• Thermostat means it only draws power when it is actually near freezing
• Integrated heater — no separate base to misalign or water to spill onto
• The most widely used heated poultry drinker in US backyards for a reason

Where it falls short

• 2 gallons is a daily refill for anything above about six hens in winter
• Needs an outdoor-rated extension run to the coop, properly protected
• A permanently plugged-in appliance in a dusty coop needs checking each season

MAXKOSKO Thermostatically Controlled Outlet, 15A 120V

MAXKOSKO

7.8/10★★★★☆Assessed on specs and owner reports

A thermostat outlet that only passes power near freezing. Put this between the socket and any unthermostatted heater and you stop paying to heat a coop in October.

Published specifications

Rating	15 A, 120 V
Type	Thermostatically controlled outlet extension
Function	Freeze protection switching
Switching temperatures	Not published by manufacturer

Specifications per Manufacturer figures as published on the Amazon product listing, as published at the date above.

What it does well

• Cuts the running cost of any un-thermostatted heater or de-icer to near zero outside freezing weather
• 15 A rating covers everything a backyard coop will plug into it
• Also an added safety layer: a heater that cannot run in mild weather cannot overheat in mild weather

Where it falls short

• Exact on/off temperatures are not published on this listing
• Not a substitute for an outdoor-rated, GFCI-protected supply
• One more connection in a damp environment to keep dry

Sweet PDZ Coop Refresher, 10 lb

Sweet PDZ

8.8/10★★★★◐Assessed on specs and owner reports

Granular zeolite that binds ammonia rather than masking it. Dusted on the poop board under the roosts it is the most effective single thing you can do about coop smell.

Published specifications

Active material	Zeolite
Weight	10 lb
Function	Ammonia and odor absorption
Scent added	None

Specifications per Manufacturer figures as published on the Amazon product listing, as published at the date above.

What it does well

• Chemically binds ammonia instead of covering it with fragrance
• No added scent, which matters because fragrance oils irritate bird airways
• A thin layer on the poop board is all it takes — a 10 lb bag lasts a small flock months
• Safe to compost with the litter

Where it falls short

• It is a granular mineral: it will not fix a coop that is genuinely under-ventilated
• Needs topping up as it saturates
• Dusty to apply — worth doing with the hens outside
