Why Winter Asks More Of Your Flock

Hens are tougher than they look, but the British winter still stacks the odds against them. Short daylight hours slow or stop laying, wet ground chills feet and combs, and long damp nights give parasites and respiratory bugs the upper hand. A hen that seems fine in October can drop weight quietly by January, because she is burning energy just to stay warm instead of putting it into eggs and feathers.

The good news is that most winter problems are preventable with small, cheap adjustments. Think of it as tipping the balance back in her favour: dry, draught-free but ventilated housing, plenty of good food, unfrozen water, and a weekly routine that spots trouble early.

Housing: Dry Beats Warm Every Time

The single biggest mistake is sealing a coop up tight to "keep the heat in". Hens cope with cold well; they cope badly with damp, stale air. Moisture from droppings and breath condenses on cold surfaces, and that is what causes frostbitten combs and respiratory infections.

• Ventilate above head height. High-level slots or gaps under the roof let damp air escape without blowing across the birds. Cover them with mesh to keep out rats and wild birds.
• Block low draughts, not the roof. Fix gaps at floor and door level. A hen sitting in a direct draught at perch height will chill overnight.
• Deep litter works well. A 10–15cm layer of dry wood shavings or chopped straw insulates the floor and composts droppings. Turn it weekly and top it up; if it smells sharp, it is too wet.
• Raise the coop on bricks or a pallet if the run floods, and check the roof before the first hard frost.
• Perches matter. A wide, flat perch, roughly 5cm across, lets hens settle over their feet and keeps toes tucked into feathers rather than exposed to the air.

Feeding For Warmth And Steady Laying

A hen eats more in winter simply to generate body heat, so this is not the time to cut back. Feed a quality layers' pellet as the main ration and let them fill up; a hen left hungry on a frosty night will lose condition quickly.

• Warm mash in the afternoon. Mix a little layers' mash with warm water — never hot — and serve it an hour or two before dusk. It gives a slow-release energy boost overnight and is a brilliant way to sneak in supplements.
• Scatter a handful of mixed corn late in the day. Maize is high in energy and digests slowly, which helps hold warmth through the coldest hours. Keep it as a treat; pellets should still be the bulk of the diet.
• Don't forget calcium. Oyster shell offered free-choice keeps shells strong even when laying slows.
• Watch the moult. Hens moulting in late autumn need extra protein to regrow feathers. A little scrambled egg, mealworms or a higher-protein ration helps them through it faster.

Water, Grit And The Frozen Drinker Problem

Hens drink surprisingly little in cold weather, but a dehydrated hen stops laying and can become impacted. Frozen drinkers are the most common cause of a winter laying slump, and they are entirely avoidable.

• Check and refresh drinkers twice a day — morning and early afternoon — rather than once.
• Use a dark-coloured or insulated drinker, stand it in a sheltered spot, and float a small sealed bottle of warm water in it to slow freezing.
• Never add salt or antifreeze. A splash of apple cider vinegar is fine, but plain liquid water must always be available.
• Keep a spare drinker indoors so you can swap a frozen one for a thawed one instantly.

Health Checks, Combs And Creepy-Crawlies

Winter hides problems. Pick up each hen once a week and check her properly — it takes five minutes and catches most issues before they become serious.

• Comb and wattles: a pale, shrunken comb suggests mites, worms or illness. A bluish tinge in bitter weather can mean chilling.
• Feet: look for mud balls between the toes, cracked pads, or the swollen, hot joints of bumblefoot.
• Vent and feathers: check for lice egg clusters around the base of feathers, and for red mite in perch crevices and corners. Red mite are dormant in the cold but will still be in the coop, so clean and dust perches now.
• Weight: the breastbone should feel firm and padded, not sharp. A bony hen needs isolating and feeding up.

If you use a petroleum jelly barrier on combs and wattles during a hard frost, apply it thinly and only when the weather is dry, not wet.

Wild Birds, Feeders And Biosecurity

The garden birds you feed all winter are a joy, but they can share more than your enthusiasm for sunflower hearts. Wild birds may carry salmonella, red mite and avian influenza, so a little separation protects your flock.

• Site feeders and bird baths well away from the hen run, and never hang them over the coop or on the fence beside it.
• Clean feeders and baths regularly with a weak disinfectant solution, and rotate feeding spots to avoid a build-up of droppings.
• Keep hens on a covered or well-drained area if wild waterfowl visit your garden pond; standing water is a known risk.
• Change footwear or use a dedicated pair of boots for the run, especially if you have walked somewhere other poultry are kept.
• Store feed in sealed bins so wild birds and rodents cannot get in.

Finally, do not underestimate light and company. Hens lay on daylight, so a small coop light on a timer in the early morning will keep production ticking over — but never extend the day past about 14 hours, as hens need proper rest. Bored birds feather-peck, so hang a cabbage, scatter corn through the litter, and give them a dry, sheltered corner of the run to dustbathe. A little attention now pays you back with healthy, cheerful hens right through to spring.
