I have three and they are quite possibly my favorite chickens - ordered some Jersey Giants to compare to them - been thinking of a good cross for them to try - maybe Giants or Australorps but not sure what would be best - anyone tried any good crosses with Langshan breed?
You can't improve on perfection. Wouldn't mess around with crossing them.
Giants and Australorps both owe much of their heritage to the Langshan and were created with heavy use of the Langshan.
