I am heartbroken as I write this but hoping for insight... My coop has been hit with a respiratory illness. One of the sickest was my x-alpha roo, a Silkie named Melvin (was also molting). Last Saturday night, he was definitely "circling the drain", so we gave Tylan 50. Surprisingly, he made a turn around and I was able to put him back in the coop yesterday. Since starting into molt he had lost some status in the rooster lineup, so I watched at first to make sure my other roosters left him alone. A couple of them chased him a bit at first then lost interest. This morning he went out to free range with everyone. 4 hours later, I found him dead ( cold and stiff) out in the yard. All of the feathers on the left side of his neck were plucked out and there were several big holes in the skin on the back of his neck. No other apparent injuries, though he had blood on his beak and in his mouth. Before I saw his body, I had noticed that there was no other chickens out of the coop and 2 of my other roosters were standing "guard" at the coop door. Several of Melvin's girls were huddled together inside in a corner. None of my other chickens have any injuries or blood on them. So any ideas? Did one of my other roosters do this? If so, will they continue to kill? Or could this have been some sort of predator? But why wouldn't it take the body? Thanks for any insights you might have! R.I.P. Melvin- You were such a good rooster to your girls! We love and will miss you!
