Hello. I work on a small acreage that has 2 male swans on it. We've had to separate the 2 because one keeps attacking the other. Last fall we were given a third male swan who was born in 2008. The young swan was put in with the one who kept getting attacked, and they were getting along for about one day until the older male started attacking the newer and younger male. Will they eventually get along or will the fighting continue? Is it a territory thing? Should we separate them? thank you in advance for your response
