Hi all, My 5 chickens are 6 months old (I don't know how many weeks exactly) and still not laying eggs. Hmmph! I thought they'd be laying by now. 4 of them are frizzle bantams, and so smaller, don't know if that makes a difference? The silver laced wyandotte and buff orp aren't laying yet either. These are my first chickens so I really have no frame of reference. Any thoughts?
