I tolerate certain species of snakes on my property. The benefits they provide far out weigh the 6-8 chicks I feed them a year. They (Gopher snakes, Rat snakes, King snakes, and Gardner Snakes) eat more mice, rats , baby gopher and squirrels than I care to try and poison. Rattlers are caught up and relocated.
The key for me has been to built as snake proof cages as possible. Then again, I have found dead, ( pecked to death) 4' gopher snakes in my pens for going in the wrong pen or getting to close to the chicks. Asils and Shamo are very calm birds.....till the "switch is flipped". ...lol!
