I just finished my coop sunday. Fully enclosed, upstairs coop. I bought three chicks and one pullet sunday as well. This morning I get up to feed and all three chicks are gone and pullett is in the coop headless. I can see where the chicks were pulled through the wire and some feathers outside the coop. They had been roosting on the ground. They had not figured out how to go upstairs. I live in north east texas and my coop is in a 8 foot wood fenced in yard. What am I up against here? Nothing got in the cage it is pretty bulletproof.
