Chicken

Domestic chickens (Gallus gallus domesticus) are descended from the Red Junglefowl of Southeast Asia, with domestication believed to have begun in Vietnam over 10,000 years ago. Today, the domestic chicken is the most numerous and widespread bird on Earth, with an estimated global population exceeding 30 billion.

In Australian backyards, chickens serve triple roles — as productive layers, as garden helpers (consuming insects, weeds and fallen fruit), and as genuine companion animals. They are intelligent, social birds that can be hand-tamed and will follow their keeper around the garden. Some breeds, particularly Silkies, are exceptionally gentle and make excellent pets even for young children.

Backyard chickens are subject to local council regulations in most Australian areas regarding the number of birds permitted, setback distances from neighbouring properties, and — critically — whether roosters are allowed (most residential councils prohibit them). Always check current local council by-laws before acquiring chickens. No wildlife keeper licence is required for domestic chickens, which are not native animals.

The most critical aspect of chicken housing is predator security. In Australian backyards, the primary threats are foxes (active at night), dogs, raptors and snakes. Chickens must be locked inside their coop each night before dark without exception — foxes will reliably find and exploit any gap, no matter how small. Wire used for coops and runs should be heavy-gauge welded mesh; standard chicken wire (hexagonal) has too large a gap and insufficient strength to deter determined predators.

Kellyville Pets recommends a minimum coop size of approximately 190cm W x 75cm D x 125cm H (75 x 30 x 50 in) with an attached run area. The coop should have a protected area screened from sun and rain, roosting perches at appropriate heights (chickens naturally roost off the ground at night), and comfortable nesting boxes for laying (one nesting box per two to three hens). Nesting boxes lined with clean straw or wood shavings should be replaced regularly.

The substrate in the coop floor can be straw, wood shavings or a sand-based deep litter system. Chickens also enjoy — and genuinely benefit from — the opportunity to dust-bathe, which is their natural method of maintaining feather and skin health and managing external parasites. Provide a dedicated dust bath area of dry loose soil, sand or wood ash.

Chickens convert food into eggs most efficiently when fed a quality, complete layer pellet or layer mash containing a minimum of 15% protein. Layer pellets should be available throughout the day, ideally in a hanging feeder kept clean and off the ground to prevent contamination and deter rodents. Soaking layer mash in water overnight before feeding makes it easier to digest and improves nutrient absorption.

Supplement the diet daily with vegetable and kitchen scraps — leafy greens, pumpkin, corn, beans, cooked vegetables and fruit are all excellent. Avoid feeding raw potato peelings, citrus peel, avocado, onion, chocolate or any salted or processed human foods. Adding garlic to the vegetable mix can support natural worm resistance and is widely recommended by experienced chicken keepers.

For foraging, a scratch mix of grain scattered on the lawn gives chickens productive activity throughout the day, mimicking natural foraging behaviour. Shell grit must be available at all times to support strong eggshell production and healthy digestion. Fresh, clean water must be available and changed or topped up daily — chickens are heavy water users. Never allow water containers to run dry.

Friendly, curious and surprisingly individual in personality. Chickens quickly learn to recognise their keeper and will follow them around the garden in anticipation of treats. Silkies are particularly gentle and tolerant of handling, making them exceptional family pets. Heritage breeds vary in temperament — Australorps and Plymouth Rocks are generally calm and sociable; Leghorns are more flighty and independent. Most hens become very tame when handled consistently from a young age.

Chickens can be hand-tamed through consistent, gentle interaction and regular hand-feeding of treats. Crouch at their level rather than approaching from above, which they perceive as a threat. Offer food from an open palm. Regular, daily interaction builds confidence and trust — a hen that is handled from chickhood will become remarkably sociable and may even tolerate being picked up and carried.

When introducing new birds to an existing flock, a period of separation — where the new birds can be seen but not accessed by the existing flock — allows a gradual hierarchy adjustment and reduces the risk of serious aggression. Chickens establish a firm social hierarchy (the 'pecking order') and new birds must find their place within it.

Chickens are natural foragers and providing opportunities for this fundamental behaviour is the most important form of enrichment. Scatter a scratch grain mix on the lawn each day and allow supervised free-ranging time where possible — a few hours of free-range foraging in a secure garden is enormously beneficial for physical and psychological wellbeing. If free-ranging is not possible, a well-planted run with rotational access to grass keeps the environment stimulating.

Offer enrichment treats: half a raw pumpkin or watermelon keeps chickens occupied for extended periods and is a useful distraction when introducing a new bird or during hot weather. Hanging leafy greens or corn on the cob at head height encourages jumping and pecking activity. Rotating the scratch area and varying treat types prevents boredom and encourages movement. A well-designed dust bath area is itself an important form of enrichment.

External parasites (lice and mites): The most common issue in backyard chickens. Red mites live in coop crevices and feed on birds at night; feather lice live permanently on the bird. Spray the coop with chicken-safe insecticide every six weeks and inspect birds regularly — pale combs, feather loss around the vent and restlessness at night are indicators.

Worms: Internal parasites reduce condition and egg production. Worming every three months with a broad-spectrum poultry wormer is essential.

Respiratory infections: Can spread rapidly in crowded or poorly ventilated housing. Maintain good coop ventilation and hygiene.

Marek's Disease: A highly contagious herpesvirus causing tumours, paralysis and immunosuppression in poultry. Vaccination at hatch is the primary prevention and is strongly recommended for all new chicks; the vaccine does not eliminate the virus but significantly reduces clinical disease and mortality.

Egg binding: Can occur in laying hens; signs include straining, lethargy and a penguin-like stance. Seek veterinary attention promptly.

Flystrike: During hot weather, flies can lay eggs on soiled or wet feathers — particularly around the vent. Keep the coop and birds clean.
