My chickens are a year old!
Rosie, the Rhode Island Red:
Penny, the Lace Wyandotte:
Olivia, the Columbian Plymouth Rock:
They produce 2-3 eggs a day, fertilize my garden, and eat my weeds (as well as my fruits and vegetables if I let them). Best of all, they are like a comedy routine in my yard.
I highly recommend getting chickens.
