You can also sell the eggs. We have two sizes - hen eggs and bantam eggs. We don't actually have any bantams but the Scots Grey eggs are quite small so that's what we call them. Our new black rocks are still laying small eggs so we add those into the boxes, although they are not quite so good as the SG eggs, which have a proportionately larger yolk. But no-one has objected. Most people prefer the larger eggs, but there are plenty who like the small ones too, for salads or children or posh parties. I am charging £1.20 for the small ones, although £1 would sell them quicker.
