Oh I am so very sorry for your loss :( You did EVERYTHING you could do, just know that. He is beautiful boy, one of the most handsome I have ever seen.
I just read your thread and wishing you the very best of luck. I lost my drake last week to a hawk (I ran over just in time to see him on the ground, with the hawk in the tree hovering over him.) He was my favorite :( I really hope things turn around. Do you have any pics yet?
