I've only ever had chickens for pets and we've never eaten their eggs. We currently have only 2 banty hens and I would like to actually eat their eggs. I know we won't get many eggs, but the few we do get, I don't want to go to waste. They haven't started laying yet. We got them this past summer. I know I have to start giving them oyster shell (I'm starting that today), but am I supposed to be giving them some sort of medicine? I read something about antibiotics. How will I know if the eggs are safe to eat?
