I don't know what is wrong with my 1 year old game hen, Ruby. She was attacked by a fox about a month ago and I gave chase until he dropped her. I put her on antibiotics for about 4 days and then she seemed fine, she started laying again, everything was going well, except the last few days I noticed that she was not going out when I let the other chickens out , she doesn't eat any treats, I tried to give her a chopped up egg and yogurt today and she wouldn't eat it. She went into the coop and I think she laid an egg without a shell. (Someone did, and I think it was her.) She has been holding her tail down and standing around rufffled up. I gave her 2 drops of poly vi-sol- no iron for good luck today. She had always been pretty skinny and our most nervous hen. Does anyone have any idea what is wrong with her? How can I help her? My 5 hens have a large penned in area and free-range around my garden every day. They eat layer pellets and have oatmeal-yogurt for a treat in the mornings. I give them a cup of crushed oyster shell whenever I see they have finished the last cup, usually once a week or so. I also give them a handful of BOSS/corn/oats as treat twice a day. I give them avia- charge 2000 once a week and I put a dash of vinegar in their drinking water.
