There is a pair of swans who recently had 7 babies. They have been together for days now and everything seems normal, until today, one of the babies started to swim in circles in the middle of the lake and the rest of them including the parents are staying away from him. They all hang around one side of the lake and the one I'm referring to, went to the opposite side of it. I went to make sure it was not stock on something or a rope, etc. and I was able to hold him and then he took off, very strong and fast. He's still away from the others. Can you tell me what prompt this behavior? should I contact somebody?
Thank you.
