Well everyone always told me don't kill the black snakes, they are good. Well last year one of those"good" black snakes was wrapped around my hubby's whandotte cockeral with half it's body swallowed up. He cost alot! Had to drive to Ohio to pick him up, where we were meeting a breeder who was delivering him from OK. Well I killed that SOP snake on the spot. As well as a few of his buddies who tried the same thing last year. Forward to last week. I find a silkie pullet dead in the barn for no reason, healthy the night before, dead the next day. Eggs slowly not being laid by hens, but it's been hot. Then my son's fav Ameraucana pullet, found dead in her cage? The next morning another silkie. They all were healthy, appeared to have broken necks. Sat morning my son comes running in the house saying there is a big snake in the barn isle. I go out & find it down under a stall. once it say me it disappeared under the barn again. I went off to run errands, when I got home I went into the barn with a flat shovel. I found the snake, just crawling off of the VERY GOOD silkie hen that I had in the stall, and yep she was dead, just like the other birds in the last two weeks. I now know what the mysterious "illness" that was doing my good show silkies in, as well as my kid's Fav bird! That 5 1/2 foot "good snake" is no more! It was leaking out egg yoke all over the place. It just killed the birds, did not try to eat them like the snake in the past, just killed them & moved on it's way. That snake in the last 2 weeks cost me a few hundred bucks in birds & eggs.
So warning to any snake thinking about entering my coops, I have a machete and am not afraid to use it!
