I am not planning on breeding anything beyond healthy, pet-quality silkies so the green eggs are probably a non-issue anyways. I just don't want anyone feeling duped.
You could say something like, "Normal Silkies don't lay green eggs, but some of these do!"
Green eggs are not the "right" color for Silkies to lay, but people who want fun backyard pets might like the green eggs better than normal ones.
