Hi, I have a real dilemma ... we have 5 hens. Two are about a year and 1/2 and the other 3 are about 7 months old. They have gotten along fine and we have had no problems in any category until the last two months. We have a neighborhood dog that the owners let run rampant ... he has killed one of my older hens by busting into their coop. That was about 7 months ago. Then he got into their coop AGAIN about a month ago and three of them into the tree line, one remained in the coop, and ran one of our older hens over close to his house where he then began to pluck her ... she put up an awesome fight and then I ran him off of her and she hid in the treeline for about a day. They all came back ... none were hurt. Since then, the one that remained in the coop, has now started shedding A LOT of feathers. She almost looks like a guinea ( sp? ) ... hardly any neck feathers, and has lost some on her wings, tail, and some on her underneath neck and belly. All of our other chickens look great ... feathers all in tact. Another problem ... NONE of them are laying. I haven't had to buy eggs in a year and now even my older hens aren't even laying. I'm sorry this is so lengthy, I just have so many questions. They are in a good sized coop ... 4 nesting boxes in a "house" that's about 4 ft tall, and 3 feet long, roof and door. They have a running area of about 4 feet wide and about 6 feet long. we let them out often to peck around and play. i am hoping this is just stress related for the one chicken. i am also wondering if i do get eggs soon, are they going to be ok to eat? Please help!! Any advice will be very much appreciated!!!
