3 days ago one of my chickens was I think attacked by a small dog, the chicken was chased at first then I think got scared flew over the pen and went down this bank which the dog followed it and I heard a yell and a scream type noise. Only the dog came back up so I looked every where for the chicken or the body but have only found a big bunch of feathers where I think it was attacked but kept finding a feather every 5 or so steps I took further into the bush. Eventually I went maybe 40m from the bunch of feathers and there was no sign if any feathers or even the chicken, I'm not sure if the chicken is dead or just scared but I have looked every where for it and don't know what to do. Can any one help me please???
