I have had chickens for 3 1/2 years and each year gets more disgusting 'cause of predators mostly. I lost 3 who were free ranging after the flood we had in May. I did not figure out what the predator was. I confined the 2 remaining hens to their pen, clipped wings again and we did okay thru the summer. Last month they were back to free ranging during the day and there had been no more problems. I bought 2 barndevelder hens at the flea market. 2 days later a dog I had never seen caught the 2 hens (one I saw and the other I only found feathers). The barndevelders were confined to the house and run because they were so flighty. Several days ago I clipped one Barnie's wing but the other managed to get away and fly out of the pen. She had done that before but she did not come back to roost this time. This morning I went to the flea market and bought 5 lovely welsummer hens @ POL from the same owner who raised the barnies. When I took them out to the pen something had caught the barnie at the entrance to the run. Lots of feathers there, none in house or elsewhere. I have electric net fencing around the chicken yard and the only chickens I ever lost inside the fence were killed by hawks: lots of blood, feathers in a trail, heads and part of upper body gone (and my hubby saw a large bird fly out of the pen during the day). I don't think this was a hawk and there is no evidence of killing on the site. I am thinking dog. The chicken had to have been killed this morning because she was on the roost last night and would not have gone to the run until daylight. I will batten down the hatches, make sure the fence has not been grounded out, set a trap etc. I would love to know what you think it might have been. I also appreciate having a site where I can vent to folks who understand!!!
