How many eggs will a hen lay in a week/year? When do they start to lay eggs?
A typical hen will start to lay eggs at about 6 months of age. The eggs will start out small, then get increasingly larger. During the first year of laying, the hen (if she is a good egg producer) will lay one egg, almost every day. The birds will then go through a “molt” in the late fall/ winter months and stop laying. Then they will start again in the early spring. You can encourage egg laying through the colder months by keeping a light on, inside the chicken coop. As the birds get older, they will start to lay fewer and fewer eggs. I had a chicken that was at least 5 years old, and she would give me 1 or 2 really big eggs a week.
