It is not uncommon for all the cygnets to be lost to predators, nor is it uncommon for most of them to survive - it all depends on the location and the natural protection afforded them. Is it normal for the parents to be chasing their cygnets once they're several months old? Once the cygnets are old enough to look after themselves the parents cut the parental ties with them and chase them away, sometimes quite aggressively.

Yes - typically in July or August each year, during which time they are unable to fly.As the parents grow older they learn from the experience of previous years. Yes, though the number of eggs laid each year tends to decrease with time. Breeding pairs do not moult at the same time as they, and any offspring, would be too vulnerable to attack.Both cygnets and full-grown swans are also the prey of foxes and mink.The nesting female has disappeared/been killed - should anything be done? The male will take over the nesting process and is quite capable of rearing the cygnets alone.
