Hi, can someone please advise regarding our ducks laying soft eggs, we have recently moved in to our own smallholding and we inherited 3 Aylesbury ducks, one duck and 2 drakes, we understand that the fox got another duck, presumably the drakes mate, anyway, we have had 2 eggs and both have been soft shelled, they are fed on layers pellets and wheat as a treat in the afternoons, do they need to be given Grit / oyster shell? they are confined to the large and I do mean large pond, but can get onto the bank for greenery etc and do have a wander round the field.
Any advice would be appreciated, thanks.
