Chicken Aging Process
Chickens mature exceptionally fast. A 5-month-old chicken (point of lay) is roughly equivalent to an 18-year-old human. Their most productive egg-laying years (1-3 years old) are their 'prime adulthood.'
💡
Pro Tips
A 5-month-old hen is biologically similar to a late teenager and is ready to start laying eggs.
Most chickens live 5-10 years depending on breed, diet, and protection from predators.
Brahmas and Orpingtons are heavy breeds that tend to live longer than high-production Leghorns.
Senior chickens (6 years+) may stop laying but still make great pets and can help with pest control in the garden.
Consistent access to fresh water and high-quality layer feed is critical for longevity.

Fun Facts
"Chickens are the closest living relatives to the Tyrannosaurus Rex—your backyard hens are tiny dinosaurs!"
"They can dream while sleeping and have REM cycles, just like humans."
"A chicken can recognize up to 100 different faces, including other chickens and people."
"A hen will turn her eggs about 50 times a day to prevent the yolk from sticking to the shell."
"Chickens have a complex language with over 30 distinct vocalizations for warning about different types of predators."
Formula: Human Age = f(Chicken Months) where f is a piecewise maturation function
