My daughter is doing a great job managing her (chicken) egg business but now we have duck eggs too... and I am finding conflicting information online. I dont want to let her sell duck eggs that might make someone sick. My questions: 1) Our ducks eggs are more than likely fertile. We have three girls and two boys. Are they safe to sell for eating? 2) We have a broody chicken hen who is sitting on four duck eggs for us. What in the world do people do with ducklings in September? 3) we have three Indian Runners (two boys and a girl) and two girl White Pekings. The ducklings will be a mixture. Is that a problem? We LOVE having ducks. They are adorable and so fun to watch! There is certainly a learning curve for us, and if she can make a little money from the eggs/ducklings I'd like to teach her how to do that. But we want to do this thing right. If we need to get rid of the mixture of the breeds.... thats something I need to know. Thank you for any help or information!
