That is true. That's why I'm using my bantam Langshan over my bantam Marans project hens to try and shrink them and decrease egg size.I just read that many other breeds were created using Langshan blood in the foundation matings. These include Marans, B arnevelders, Black O rpingtons, and Jersey Giants. Maybe that's why we see some of the Langshan characteristics popping up every once in a while!
