That is from a raccoon. They will typically tear off the head and toss it aside someplace then eat the insides and breast area. usually you,ll have a wing, leg or two left of the dead bird. Take precautions immediately cause it or they will be back until all your birds are gone. I have my coop inside of a large dog fence. Around that fence I have the run secured with a double layer of wire and rocks so they cant dig under or yank the birds thru the holes in the fence.....yea...they do that too, however, I have several small trees inside the run so the birds have shade. Some of the branches extend out and over the coop to neighboring tree branches, and wouldn't you know the raccoons used the trees like squirrels to get into the run and ultimately the coop at night, when the figure out the puzzle.... I've used have a heart traps to catch them using cat food as bait, but you,ll never get all of them like that....The most effective way is too drop a bag of corn down and sit with a rifle. Between the hours of 9 to midnight is when I have the most success and can see just how many are in their clan. I have had as many as 5, feeding at one time on the corn. Once you get rid of them, you,ll be good for a year or so until they repopulate the area, extend their range and find your food supply.
To give you an idea of how smart and organized they are....I buried some fish in my garden once about 18inches into the ground, then started to notice holes in my garden. I set up a camera to see what was creepin and at night the raccoons would come. Some would dig up the fish and pass it off to another raccoon who would transport it into the woods....until all the fish was dug up. That's probably why they wear that mask.....straight up thieves....lol.....anyway I hope my experience is helpful.
