I have three hens laying right now (and a bunch of pullets that should start in the next few weeks). The hens are about 2.5 years old, one is a salmon favorolles, one is a red star, and one is a BO. The hens are on Layena pellets, but free range all day most days. The eggs are perfect, but they're not terribly big, I'd call most "small" in grocery store sizes. What's up with that? The eggs I get from the farmers market are about twice the size of the ones my girls lay, although that seems to be mostly due to more whites, not bigger yolks.
