I had one chicken get carted off last week - dragged up the side of the enclosure and taken just a few feet away and not much was missing. We assumed raccoon. We have chicken wire on top of the entire coop although there is a skinny space where the door opens that can allow predators to get in. This morning, I went to feed my chickies and there was a huge pile of poop on the door. Here's a couple of pictures - it's unlike any I have ever seen (thinking bird?). Please help me identify so we can find a better way to keep our chickens safe!
