FAQ

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.

裏庭で飼う採卵鶏はどれくらい生き、どれくらい産卵しますか。 — University of Wisconsin–Madison Extension は裏庭の群が 6〜8 年生き、多くの群が 3〜4 年産卵するとしています。Colorado State University Extension は産卵 2〜4 年、寿命は最長 7 年としています。両者の範囲は近いものの完全には一致せず、方法論と統計母集団が異なるため、独断で 1 つの数値に折衷すべきではありません。

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.

肉用鶏を普通のペットとして高齢まで飼えますか。 — 肉用鶏は短期間で急速に増体させるために育種された系統で、コーニッシュクロスはおよそ 6 週齢、成長の遅い系統はおよそ 8〜9 週齢で出荷体重に達します。自然寿命まで飼うと骨格と心血管系の負荷を超えることが多く、これは裏庭の飼い主によくある誤解です。

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.

ガチョウを飼うときの注意点はニワトリやアヒルと同じですか。 — 同じではありません。ガチョウは放牧、番、観賞が中心で縄張り意識が強く、飼う前に人や他の動物への攻撃リスクを評価する必要があります。ガチョウの寿命はニワトリやアヒルより長いと一般に理解されており、飼い主は飼育年数の見積もりを過小評価しがちです。アヒルは正常な行動を満たすために水に触れられる環境が必要です。
