Thank you so much for your response. I was hesitant to contact anyone because NY is one of those states that wants to eliminate mute swans and I do not want the location of the other swans to ever be known, we have fed and loved them for many years. I will pray that she heals and is able to make it on her own… while each year the brood has suffered loss (last year the entire nest) somehow this is just so much sadder considering how grown she is at this stage. Thank you again for providing me with an understanding of what is going on, truly appreciated.
