I just killed a chicken snake the other day when it was on my fence going into the chicken pen. Darn thing was within inches of my ehad and scared the crap out of me. Each day we go out to check on the babies we find one dead in the cage. It's head is wet and my husband couldn't figure out what was going on. Well, I know!! It's another chicken snake! I caught him in the act just a few minutes ago and chopped him in half. It was too late he already killed another chick. That makes four out of sixteen. Going to the Farm Supply tomorrow to get some SULFUR to stop this once and for all. I will put a line of it outside the pen and another line inside around the coop itself. I just let them out of the cage today to start getting use to the coop and now the little things are scared to death in the cage and out of it. They aren't safe anywhere. What good are the grown chickens if they won't protect the young ones? The only good chicken snake is a dead chicken snake!!!
