You really should call the Parks and Wildlife Service where you live and have the snakes relocated.  Killing them or keeping them without a certain stamp can land you in big trouble.  Not to mention the snakes are not hurting you... just have them relocated.  Personally I hope you get caught and get that big *** fine and get taught a lesson.
		
		
	 
Obviously you either don't live anywhere near here or you live in a city.
However, Protecting ones farm (livestock and crops) from local wildlife is protected under state law in most places as long as rules are observed in doing so, That being said, the minnow trap is a "Live Trap" and as such is a very humane way to capture whatever might happen to get into it and relocating or dispatching whatever you catch would be up to you, 
Where I live the local game wardens have more important things to do than relocate every snake that gets into someones henhouse and most likely wouldn't even respond to the call other than to tell you to kill or relocate the snake.
I have literally caught dozens of snakes with the minnow traps and most were caught without using any kind of bait, the venomous ones don't get to be relocated and most of the others get to live somewhere else,
I moved recently and the traps are going to be used mostly to catch minnows on fishing trips for a while until I need to use them for something else and I will have chickens to protect again at some point.
It might be really educational for you to call or go by your Wildlife department and look into the rules concerning these issues and see what options land owners and or residents have.
It would certainly be more productive and kinder than wishing bad things on people you don't even know...
 
	
		
	
	
		
		
			I tried this last year and it did not work at all!  Wasted my money on these traps.
