Hi Betty
Yes, the behavior you are describing is normal swan behavior in cygnets that are now ready to mate and have no idea how to deal with the increase in sex hormones. We have seen mating behavior in cygnets as early as 1-2 years of age. Are all of of your swans clipped? Are there any predators in your lakes that a clipped swan cannot escape? If the answer is yes to question number one, then you might consider clipping and relocation to another area pond. However, if the answer to predators is yes and no escape, you need to consider which lake you can safely relocate because relocation can result in serious injury or death to the cygnets if they cannot fly and escape predators. Sex hormone levels should return to normal levels in a few weeks and the cygnets’ behavior will settle. The Regal Swan
