Backyard breeders or BYBs have many tactics. The braver BYBs show the animals and sort of admit it which I feel is a tad more open than the other type.
The sneaky ones do not show any animals. They pretend they are not the ones doing it and always say they know someone who has some animals, etc, etc, etc, etc and more etc.
But then if you are a BYB, you are definitely a BYB not a YB.
(Gosh, I love to pun.)
