I have 3 duck eggs but I honestly don't know how far a long they are...I know that they are at least 2-3 weeks. I know you are supposed to stop turning the eggs 3 days before they hatch but how can I if I don't know how old they really are...what if I stop turning them too soon or too late? does anyone know any sites with pictures of embryo's or candleing so I can compare?? please help me I've looked every where!
