Hi.. I am new here and I have a question. I have 9 regular chicks (4 dominiques, 4 yellow stars and 1 Rhode Island Red) that are 4 months old and one little red banty hen that is 4 months old also. The banty started laying cute little brown eggs 2 weeks ago. Isn't she too young? I read that most chickens start laying at 6 months. Also, on three different days I have found 2 eggs in the nest. Two of the second eggs were small like the banty, but the second one on one of the days was large like a regular hen egg. Is this normal?? Thanks for any light anyone can shed on this for me.
