Orpington owners, look here<--------------------------------

Supposedly, the Orpingtons will continue to grow and mature for 18 months or more. My Blue Orpington, Suede, is right at 12 lb. Haven't weighed the girls in awhile, though. One standard I read said cocks were 10-14 lb for the blues and 10-12 lb for the Buff roosters, but I think the U.S. standard doesn't call for the upper range of weight.

The Orpington Club has a breed standards page with weights for both bantam and standard varieties. Is that what you need? (they also have pullet, and cockrel weights)

That's great! I may have to look into that!
