my girls lay eggs continually which i thought was not normal. my first batch only laid in Jul/Aug then again after Christmas. these new girls are laying all year round. i eat them boiled, poached, scrambled. my partner won't eat them if he sees them first. i sell them in my shop and have a couple of regular buyers for them. one of the ladies pickles them in vinegar.
don't know about cakes as i don't bake cakes. ducks are usually one for every two hen eggs.
