I have had chickens for about 8 years and have never lost any to illness. Three weeks ago one of my 3 year old Easter eggers looked like she had dropped dead in my chicken run. Day prior she was fine pecking and hunting bugs with the best of them. Today I found my one year old silkie had died in the night. No signs of a predator. I keep a small flock (16) and a clean coop.first hen felt heavy so I feel like the was no weight loss. My silkie was pretty small even by breed standards so it seemed hard to tell. No outside signs of infestation or infection. I have not put any pesticides out, but two chickens in three weeks bothers me. It has been a very wet year for us in Kansas but other than that I’m doing nothing different. Ideas or suggestion would be greatly appreciated.
