How long do backyard laying hens live, and how long do they lay?

University of Wisconsin–Madison Extension states that backyard flocks may live 6 to 8 years and that most flocks lay for 3 to 4 years; Colorado State University Extension gives 2 to 4 laying years and a life expectancy of up to 7 years. The two ranges are close but not identical, their methodology and study populations differ, and they should not be averaged into a single figure.

Can a broiler chicken be kept as an ordinary pet into old age?

Broilers are lines bred for rapid short-term weight gain; the Cornish Cross reaches market weight at about 6 weeks of age and slower-growing lines at about 8 to 9 weeks. Kept to its natural lifespan, a broiler often exceeds what its skeletal and cardiovascular systems can carry — a common misunderstanding among backyard keepers.

Are geese kept the same way as chickens and ducks?

No. Geese are kept mainly for grazing, guarding and ornament, are strongly territorial, and their risk of aggression towards people and other animals must be assessed before you take them on; geese are commonly understood to live longer than chickens and ducks, and keepers often underestimate how many years they are planning for. Ducks, in turn, need access to water to meet normal behaviour.

This record notes the source location and content hash of "Backyard Poultry｜Group Overview", so the text can be checked against the original.

How to use this record to verify

This record exists so that anyone can check for themselves whether the text has been altered. Every chapter of the veterinary encyclopaedia carries a starting line number and a content hash (the first 16 characters of its SHA-256). Recompute the hash over the original chapter: if it matches the value recorded below, what is published here is identical to the source chapter. The source list at the end is the authoritative material cited by that chapter — a chapter-level correspondence, meaning those sources underpin the chapter as a whole rather than mapping sentence by sentence. This is educational information and cannot replace a practising veterinarian; in an emergency, seek care immediately.

This record notes the source location of "Backyard Poultry｜Group Overview | Evidence chain": the section beginning at line 50 of `26-T7-家禽.md` in the veterinary encyclopaedia. The SHA-256 of that section (first 16 characters) is `04a34016ddef1378`, which anyone can recompute to confirm the content has not been altered.
