Well, I started with Langshans, and after I got them the breeder said that in general Langshans were too large to be able to use a roost without leg problems developing from jumping down off the roost. The original cockbird and his replacement offspring became lame over time. As this breed was known for being able to fly and roost in trees when first imported, I consider this an example of bad breeding for the sake of other traits rewarded in the show ring.First I'd like to see some actual evidence that certain breeds of chicken absolutely do have certain health problems.
I asked the OP twice to validate her claims of birds being in pain with scientific evidence. She chose not to.
Lots of pain when being forced to run by another more dominant not lame cockbird. If they didn’t have pain they would not be spending most of their time not using their legs.
