I don't know anything about these particular cochins or the cochin standards, however, I can vouch for the breeders. I have bought birds from them in the past and can guarantee they will be clean as a whistle when you get them- no lice or bugs. At least all of mine were in great condition when I received them! I've never been dissappointed with any I've purchased from them. They even sent me a check after I purchased some birds and paid a few dollars too much on shipping.
If you have any questions about faults, just contact Steve or Brenda (Maplewind Poultry). They will be completely honest with you and tell you what you're getting. They are very knowledgeable and great people to deal with.
