Very interesting read. I really do enjoy knowing these things, though I am a Christian. Leviticus gives us the same directions on food consumption, but being "Gentile" gives a much broader leway. Anyway, I was going to say, you can tell the difference between silkie eggs usually. If you want them as pets, just do not keep cockerels. If you keep only hens, then you will be able to separate their eggs out. I have 20 birds, and I know who lays what egg. I have always been able to tell the silkie eggs from the others. They are a small/medium egg, off white to creamy in color. Since you can not make profit off selling them, you could just donate to food banks/charities that do not follow Jewish strictures maybe? Or scamble them up in a pan and utensil specifically for use only for those eggs and feed them back to dogs or cats. You aren't going to eat the dogs or cats... Just don't feed them anything dairy at the same time? Or better yet, get older silkies that are no longer laying, or lay so sporadically that you won't have to worry of non kosher eggs? I have a silkie who is going on 3. She lays egg every other week or so. LOL. I swear where it happens she is stunned!
