We have killed 4 rat snakes and have caught 2 mice every night in our reusable traps (wish I had more than 2 traps). This is just for the month of May! Much less the ones from April. These things are making me crazy. I can't walk in my coop without seeing a mouse or a snake or a snake eating a mouse. The burrows are everywhere. We got rid of all our scrap wood, got the whole yard cut short up to the wood line, 50-60 foot away. I think a main issue is the soy bean field they left over winter and just plowed down last month. I can't take it. Spread sulphur around today, what else can I do. I have chicks hatching soon, bantam babies, and can't do this. I am making raised cages starting this weekend so that they aren't sitting ducks on the ground, since my silkies don't roost.
