At what age are chickens considered adults and can be fed adult foods?
Between 16 and 24 weeks generally speaking, chickens are said to be adults when they reach the point of sexual maturity and begin laying eggs. This typically occurs when the chickens are between 16 and 24 weeks of age, depending on breed, but even some individuals within a breed will develop more quickly or slowly than others. That being said 18 weeks is a good age to start them on oyster crumbles for that extra calcium (off subject but wanted to throw that in).
