I have, or I should say I had, a silkie chicken. I went into the chicken shed and there was a 5-6 foot black snake sucking on my dead chicken's head. The rooster did nothing to help her. WE tried to catch it but it slipped away. I wish I had killed it. We had a rat problem, and I would gladly of given up some eggs to have the rat killer, but it is killing my chickens!! Someone told me to put lime around the chicken shed doors. Will this help? What do I do? Wht kind of bird might kill a snake like this? Would a peacock? HELP!!
