They are 5 1/2 months. (So 23ish weeks) I have one cochin bantam that is 2 weeks younger than them and has given me a tiny egg every day for the past four days.Ugh, I've read about Orpingtons going up to 29 weeks before an egg, and I look away. Wonder when. How old are they now? (orpington and sex link).
