I am sorry for your loss. I have a mixed pet area and it is impossible to keep things from happening all the time. For the most part the strong or maybe just lucky, survive. No matter what, a loss is incredibly sad. Some examples are like that my Llama has accidently stepped on a couple of chickens....and I actually shut the lid on a feed barrel and didnt know my Special Needs hen Bloodhead was inside - she ate herself to death, no kidding! Literally stuffed herself stupid and croaked. One close encounter happened when my Black Copper Marans, BC, was a youngster - for some reason I wandered out to the coop at about 11:30 at night...and there he was hanging from a hook on one of the roosts. His Legband had caught on it, and he was suspended in the air, just looking at me??? I dont think he would have been okay upside down all night. And Tubby, my now indoor rooster, got his name from falling in the water tub, twice, as a chick. He's actually not smart enough to live outdoors.
So, the unexpected will happen. We have had heavy losses from predators (hopefully reinforced enough now) and worse, from my own dog (she's gone now)....I hope to be able to settle down with the plans I have for my flock, for pretty eggs, and breeding projects....but losses happen. Running into walls, falling in water tubs, getting stuck in places....what are these chickens thinking??? But you gotta love em!! Aren't they great?
Hope you feel better, your rooster was a beauty! I can tell you cared for him a lot. Thank you for sharing his story.
