It looks like the little Barred Rocks just like to crow late. I had one who is now about 16 weeks and the little guy hasn't even made an attempt to crow. Had two Lakenvelder's of the same age who started a few weeks ago and crow constantly. I gave the the Barred Rock to my mother since I only have room for one roo and he is just a doll. He is happily mating with his entire harem constantly and still not a hint of crowing.
