Actually we do, there usually peaceful and rarely come near our house. One was caught in our neighbor's backyard and weighed 49 pounds!! Anyways, I don't think it was a snake; I didn't find their heads damp at all. Sorry, about your chicken.
This morning I found one of my chickens and my alpha rooster on the ground of their chicken coop! I tried finding out what could have happened to them but I couldn't figure it out. There were no sign or symptoms pointing to sickness- the day before they were cheerful as ever and they hadn't lost...
