The 'two years' part is only an example, since it varies. But curious, when we talk about egg-laying capacity, are we talking about from the time the bird hatches or the time the bird has actually started to lay eggs? Example, (only example) - buff orps may lay for two or three years, is that two or three egg laying years, which is actually when they may be 16 weeks old OR is it two or three years from date of hatch? Just looking for what we all classify egg laying as. Some posts say 'when the chicken is two or three years old' other posts say 'they stop laying after two or three years'
