I know how traumatic it is to put them down. I have done it myself and after finding someone that will do it for me, I am sold. A humane killing is always the best option. The bird gave you their best and now it is time for you to give them yours. I am super sorry.Thank you guys so much for all of your kind words. This is heartbreaking but I'm glad he'll be going to the vet where I'll try and comfort him as it happens. He's been an amazing rooster, very proud of his flock and his son, Bruno will now be taking over for him. We will give him a nice burial and will be respected like any living being should before his time comes.
