I have 2 girls that are around 23 weeks old, or 5 1/2 months. a little more than that. they are a white leghorn and a bsl, and arent they supposed to lay at like 5 months? ive heard of posts where those breeds are as early as 15 weeks! is this normal? am i just being a nervous nelly? thanks for the help. and by the way--- they are on layer feed and have had the world's reddest faces for months now!
