Ok, I thought I would ask you locals this question. Should I be worried about rattle snakes now that I have chickens? I live in Casa Grande and our neighborhood cul-de-sac opens into the desert. And we have seen a few. Or am I being paranoid?
I can not find anyplace a % guide to the size of an animal a snake can eat, Relying on hear I have seen, a full size mouse eaten by a king snake maybe 13"-15" long it had a hard time getting it down. I would say if you have small chickens yeas, but no not rally, it would be a very big snake. There are non-native constrictors that are feed chicks. As for getting bitten that is smoothing else. Snakes do not like to us there venom for anything else but food.
A friend of mine yrs. ago, brother was bit twice. First bit was dry, the second had enough venom to miss up his day. They were in Tucson, got anti-venom, but the dry bight was infected. I do not remember what kind of infection.
My suggestion so try to keep what they want unavailable to them, Water. They need water, their food needs water. Cover, places that they would love to he'd in.
