Question & answer

Do Bantams, Silkies or Molting Hens Need a Heater?

Sometimes for bantams and molting hens, and no source says so for Silkies. The University of Maryland Extension names bantams and molting hens as birds that may need supplemental heat or protection when large fowl do not. For Silkies, the one extension text we found asks for shelter from foul weather, not for heat. The University of New Hampshire Extension suggests insulation for small breeds and advises against heat sources because of the fire risk.

Straight answer

Bantams and molting hens may need extra heat or protection, according to the University of Maryland Extension: bantams produce less body heat than large fowl, and molting hens lack feathers until they grow back. No source read for this page says Silkies need a heater. A University of Georgia extension tip says their feathering makes them unsuited for foul weather, so dry, draft-free shelter comes first.

Three groups, three different answers

The general question, whether adult chickens need heat at all, splits the extension services. That debate is laid out under do chickens need heat in the winter. This page looks only at the birds the sources single out.

Bantams: less body, less heat

Maryland gives the reason in one sentence: bantam breeds do not produce the same amount of heat as large fowl breeds. In a mixed flock, it adds, you may find that the bantams require supplemental heat while the large fowl seem perfectly comfortable.

That is a “may”, not a rule, and New Hampshire answers the same problem without a heater. It writes that larger breeds are generally the hardiest and suggests that keepers of smaller breeds like bantams consider insulating the coop. On heat sources it is clear: the risk of a fire is too high with combustible bedding present and given the tendency of chickens to knock things over.

So both camps of the wider debate show up here in small. One source allows heat for bantams, one prefers insulation. Wisconsin describes the debate as ongoing and expects that many keepers of small flocks will want to provide some source of heat.

Molting hens: a gap in the insulation

A hen in molt has lost part of the feather cover that keeps her warm. Maryland writes that such hens may need some extra heat or protection until the feathers grow back in. Note the second word: protection. A place out of the wind, dry bedding and a spot on the roost between other birds are protection too.

The sources give no temperature for this and no number of weeks.

Silkies: the issue is wet, not cold

Silkies are the bird this question is asked about most, and the sources say the least about them. None of the winter fact sheets from Maryland, New Hampshire, Ohio State or Wisconsin names the breed.

The one extension text we found is a backyard flock tip of the University of Georgia Cooperative Extension Service from January 2009. It calls the Silkie the most popular bantam breed in backyards and says the birds will survive hot or cold weather, but that because of their fancy feathering they are not suited for foul weather.

Read together with the other sources, that points to three things:

  • A Silkie is a bantam. Maryland's sentence about bantams and body heat applies.
  • The feathering has to stay dry. That is a job for the roof, the run cover and the waterer, not for a heater.
  • Crests and feathered feet collect ice and snow. Wisconsin says so for crested and feather-footed breeds in general and mentions nipple waterers as a way to keep crested chickens from getting ice on their crests.

Whether Silkies need a heater is therefore not something a source answers with yes. More on breeds and feather types is under cold-hardy chicken breeds.

What to do first

  1. Check the coop, not the thermometer. Dry bedding, vents near the roof and no draft across the roost come before any device.
  2. Consider insulation. It is what New Hampshire suggests for smaller breeds, and it needs no power.
  3. Watch the birds. The signs of cold stress that extension sources describe are listed under how cold is too cold for chickens.
  4. Add a warm spot only if the birds show they need it. Make it something they can walk away from.

If you decide to add heat

For one or two birds, the smallest step is contact heat: a low-wattage pad that warms the bird resting against it. It is described under heated pads for chickens.

For a group of bantams on a roost, a flat radiant panel on the wall beside the roost warms the birds next to it and not the coop air.

Our pick for coop heatAd

Cozy Products

Cozy Coop 150 W panel

A 150-watt flat radiant panel from an established brand that warms the birds next to it instead of the whole coop.

Why here: A closed 150-watt panel that mounts on the wall beside the roost, ETL-listed for zero clearance according to the manufacturer. It has no thermostat, and birds that do not need it can move away from it.

Best for: Keepers who have decided to add gentle heat near the roost and want a panel with a manufacturer-documented listing mark.

What speaks for it

  • ETL-listed for zero clearance, according to the manufacturer
  • Mounts on a wall through keyhole slots or stands on the included feet
  • 150 W, against the 250 W of a typical heat lamp bulb
  • Cord is coil-shielded, per manufacturer

What to know first

  • No thermostat: a cord switch sets half or full power (instruction sheet), so it runs whenever it is switched on unless you add a thermostat outlet
  • The instruction sheet says “household use only” and dry areas only, while the NFPA asks for equipment made for agricultural or commercial use
  • 6 ft cord: needs a fixed outlet close by, because extension cords do not belong in a coop (NFPA)
  • Warms only birds within reach of the panel, not the coop air
  • Still a heat source next to bedding and dust: lower risk than a lamp, not risk-free

A panel is the lower-risk device compared with a heat lamp, not a risk-free one. It needs fixed mounting and a fixed outlet: “Do not use extension cords in the coop,” says the NFPA tip sheet. The panel types are compared under radiant panel heaters.

One caution that follows from the sources: heat for the whole flock because of one small bird is the wrong size of answer. Maryland describes exactly the case in which the bantams need help and the large fowl are comfortable. A local warm spot serves the first group without changing the coop for the second.

Questions keepers ask

Are Silkie chickens cold hardy?

The one extension text we found on the breed, a backyard flock tip of the University of Georgia Cooperative Extension Service, says Silkies will survive hot or cold weather but are not suited for foul weather because of their fancy feathering. It names no temperature. The practical reading is that Silkies cope with cold as long as they stay dry and out of the wind.

Do bantams need a heat lamp in winter?

No source read for this page names a heat lamp as the answer for bantams. The University of Maryland Extension says bantams may require supplemental heat and warns in the same publication that even heating lamps can cause fires if not properly secured. The University of New Hampshire Extension suggests insulating the coop for smaller breeds instead. If you add heat, a closed radiant panel or a heated pad is the lower-risk device.

How long does a molting hen need extra protection?

Until the feathers are back. The University of Maryland Extension writes that molting hens may need some extra heat or protection until their feathers grow back in. It gives no number of weeks and no temperature. Any figure for either is a keeper's own rule and not a sourced one.

Should I separate a bantam or a molting hen to keep it warm?

The extension sources read for this page do not answer that, in either direction. They describe extra heat or protection for the bird and say nothing about housing it apart or about moving it between a heated room and a cold coop. Because no source covers it, this page gives no recommendation. A bird that seems weak or ill is a case for a veterinarian.
