My dh was working on the attached run to our chicken coop. We had just put in an automatic pop door in the coop. My dh covered the pop door with a board leaving an inch on the bottom and an inch on the top. The scrap of wood nailed over the pop door area was to keep a coon, dog or coyote from pushing it in until we get the attached pedator proof run complete. We decided to test the pop door and found that the chickies were scared to be anywhere near that end of the coop. We decided while we were outside working next to the coop to leave it open so they could get use to the pop door. Well my husband is right next to the coop and pop door, on a ladder and her comes a 3 ft bull snake slithering along the coop. Yikes! The snake goes under my dh ladder up to the pop door. My dh jumps down and with his hammer scoops him up and throws him away from the coop. He asked me if I wanted him to kill it. I said no, just leave it alone. I then walked up to our garage to pick up a tool and there was another bull snake trying to get in the walk in door of our garage!! We had just cleaned out the brooder in the garage and moved it to the coop! Did these snakes smell the chickens? Can they kill 6 week old chickens? I didn't kill either snake but maybe I should? Two snakes in one day!! One trying to get in coop where the chickens are now and one trying to get in the garage where the chickens had been!! We had snakes around our patio before we had chickens. They would sun themselves and then disappear. Never did they try to come near the house or garage. I hate snakes but I hate mice more so I left them alone. And they left me alone. The photo above is of the snake from last spring (before chickens) sunning himself near our patio.
