I found a pile of feathers under a large tree, then a trail of them ....the hen is missing .... which predator does this ?? I set a live trap, and nothing has been caught for 3 days ..... I have a few birds that free range, the others cant fly over the fence ..... This predator hasnt come back .... not a dog, as the feather trail led to the cliff we live on ... I'm guessing raccoon or possum ... wouldnt they be back by now to try for more chickens ??
