Backyard chickens in Australia — what to know
Keeping chickens is legal in most Australian councils, but rules vary. Most metro councils allow 5–12 hens (no roosters) without a permit. Always check your local council's regulations before buying chooks.
- Breed matters a lot: An ISA Brown can lay 300+ eggs in her first year. A Silkie might manage 150. Pick your breed based on whether you want maximum eggs or a pet that occasionally produces breakfast.
- Production drops with age: Hens lay best in their first 2 years. After that, production drops roughly 15–20% per year. By age 4–5, many hens lay only a couple of eggs a week.
- Winter slump is real: Chickens need 14–16 hours of light to lay consistently. In southern Australia (VIC, TAS, SA), winter production can drop 25–40%. Some keepers add coop lighting, though this is debated.
- Moulting: Once a year (usually autumn), hens shed and regrow feathers. During moult, laying stops for 4–8 weeks. It's normal — they're redirecting energy to feather production.
- Diet and stress: Layer pellets, calcium (oyster shell grit), fresh water, and a calm environment all boost production. Free-ranging helps but isn't essential.
🦘 Fun fact: Australia has roughly 25 million laying hens commercially — about one per person. The average Aussie eats around 250 eggs per year, making us one of the highest per-capita egg consumers in the world.
