hi everyoneI have never seen a gardner snake large enough to eat a chick. A small egg, yes, but a chick, no.
Even a bantam egg would be hard to get down for most snakes in Western WA.
Now if you're in Eastern WA - it's a different story.
i lived in SC for many years there are no snake big enough out here in western WA to eat a egg or snake. The rat snake in SC could and i have seen five to six feet long. They would kill one quickly and they were not even poisonous. There many different poisonous kinds.
