Rhode Island Red hens lay light brown eggs that are medium to large in size. The color of the eggs is determined by the breed of chicken, not by the color of their feathers. Rhode Island Reds are known for their egg-laying abilities and can lay approximately 270 light brown eggs per year, which is about 5 eggs per week per hen. The birds typically begin laying when they are between 4 and 5 months old. The size of the eggs will increase as the hens get older.
