It seems to be the natural order of things. I had a rooster I plan to keep die on me a few days after I butchered several others. I have a two chicken limit in my residential area, and my 5 month old roosters were getting loud even with rooster collars.
I have two Jersey Giant hens, two Australorp hens, and three Orpington hens left. I was planning on keeping my Jersey Giant line going, but found my Jersey Giant rooster stiff on the floor of the coop one morning. The first think that came to my mind was, "Why did god take him?" I reasoned that he thought it would be better if I crossed a rooster from my Barbeziuex hatching eggs in my incubator with the Jersey Giant hens. I also thought that he may have took out the rooster because my neighbors were getting annoyed. If they complain, I would have to get rid of all except two chickens and the second offense would be up to a $1,000 fine.
Anyway, the point I trying to make is everything that happens happens for the health of the universe. According to William Law, "If we thank and praise good for everything that happens to us, we actually turn it into a blessing. We could do no more for our selves then by this thankful spirit, because it turns all that it touches into happiness."
