i have two very large English Orpington hens whom I really love. They're huge and fluffy, generally curious and friendly, and they are. Is each laying 4-7 pale brown eggs weekly. Can anyone tell me how a White Rock hen compAres to an Orpington? Barred Rocks seem somewhat smaller than my Orps; Are White Rock hens built more like a fluffy Ofpington or a a bit leaner like a Plymouth Rock? Also, when do White Rocks tend to mature and what's their egg production like? Last, the store selling the White Rock chicks in our town claims they've all already been sexed as pullets at the hatchery. Was this sexing likely done via vent or are there feather or other way to determine the gender of a White Rock chick? Thanks!
