I read what predators do what to do the chickens but just went out and found four of my 3 mo. old chicks huddled on my deck. I looked for my white silkie and couldn't find him. I went to the coop and there was blood and some feahters splashed on the outside. Then in my garden were a ton of feathers with some blood but no parts..no wings, no head, nothing. just feathers. additionally, my boxer is great with them and protects them but its too cold for her to be outside. will the blood and feathers trigger a prey drive in her???
