I caught a 5 foot black snake in the act at 1 am this morning. It had already killed 3 of my 4 week old chicks. It had swallowed the head and neck until the they smothered and the acid kicked in then spit it out and started on another. I killed it with a hatchet. It went after the big chicks. BCM,Brahma and Polish. It left the smaller Ameracuanas. Do moth balls really work? Thanks.
