Our speckled Sussex rooster 1 yr old, just suddenly died. No reason that we could tell. 
We noticed this morning that he had dried blood on his comb.
We have never seen him fight with our other rooster, so I can't think of what could cause this. Over the winter he lost most of his comb from frostbite, but other than that, he seemed healthy.
He had one leg with bad scaly leg, some of his underneath feathers looked like they had been broken off around his neck area, I only noticed is when I was searching for signs of injury. I found none.
Any thoughts??
