I too feel your pain on your loss! My Rooster Fearless, one of my first 4 chickens got nailed by a scorpion before he killed it and fed it to his girls. Sadly, he passed on after about a half hour, in my arms. That was Sunday, today my gold laced wyandotte Copper was dead when I came home from work.... No idea if it was a scorpion too, but we really don't have that many in our yard. Pest control hubby does a sweep at least twice a week with the black light.
Had someone told me a month ago I would be having a rooster shortage, I would have laughed in their faces... UGH. SO, I am ISO an adult rooster (breeding age, not too old) for my girls. I am in east mesa. Let me know if anyone has any roosters....
edited to add: I have read/heard that benadryl might help if caught fast enough.
