I'm a new chicken rancher, with 13 nearly 3-month-old chickens - 6 red hens and 7 silkies. We had chickens when I was a child, so I'm tuned into predator issues. I thought I had my coop very secure, but did not anticipate snakes small enough to get through one-inch chicken wire trying to eat something too large. I thought weasels and raccoons would be the most difficult issues. Within in the last 2 weeks I've lost 2 chickens to blacksnakes which strangled them but couldn't get them down due to size. Even though I am ecology-minded, and appreciate the balance of nature, I kill snakes that come in the coop. Today I caught a third snake targeting the group, and eliminated him. An ounce of prevention is definitely worth a pound of cure, so tomorrow I will reinforce my one-inch wire with hardware cloth. I'm getting too old for all this violence.
