My BO started laying this past Monday, at exactly 24 weeks. Since last Thursday I've gotten 7 eggs between the 2 of them! The Australorp makes a neat little bare spot in the corner of the nesting box to lay, the BO makes a huge mess in the hen house and I have to search for them! But she's given me 3 eggs in 3 days, good girl! The Brahma and Easter Egger are still trying to figure this all out.
