Sarah is a slightly overweight 2-year old BO hen. We separated her from the rest of the (free-ranging) flock 9 days ago, because she was sneezing and did not seem her usual bossy self (she's one of the top hens in a flock of 20). We treated with Vet RX for the respiratory symptoms, and Tylan 50. We've offered her every one of her favorite treats (yogurt, cornbread with raw goat milk, apple sauce, scrambled egg, oatmeal, etc), but she will only eat watermelon and raw egg. There has been no improvement whatsoever of her respiratory symptoms, her breathing is heavy and when we pick her up, she is wheezing. Her poop is green and white. Today I tried to let her out of the cage for a while to get some sunshine outside, and noticed that she was limping. There is no sign of injury, but she seems to have no feeling in her right leg whatsoever. Also, her right eye closes when she gets tired, while the other one stays open. I'm at the end of my wits, and grateful for any suggestions. Thanks, chicken peeps!
