I have had swans (pairs) for 6 years. After my cob was killed last year I got a new one. He is 4 years old and was hand raised. It is mating season and although we have had to deal with aggression from our previous swan, he would reluctantly back down. This cob will not at all. Our pond is several hundred feet from the house and today the cob came to the house and tried to attack through the window. We certainly don't want him to hurt himself. We also can't go outside anywhere on our 5 acres without him coming at us. I love keeping my swans, but my husband has about had it. Is there anything we can do?
