A sad day in the backyard

Well, it was a bad couple of weeks for us...we have had our three hens for a couple of years now and regularly let them out in the yard to free range and then lock them back in their coop at night. Two weekends ago one of our girls didn't come back, we weren't sure what got her, but found a small pile of her feathers just outside the coop. We were all upset, but thought it's the cycle of life and some animal, maybe a fox or something opportunistic grabbed her. Then, last Sunday, my wife and kids were walking down the steps and something brought her back and left her in the side of the yard....that really shocked us. So now we are just confused, maybe a dog would do that, but I don't know....just not sure why something would of attacked her and then brought her back a week later...needless to say I buried her under a flowering pear tree on our property, which made the kids feel at least a little better about it

Rest in Peace Maria
