My 2 and a half year old Golden Laced Wyandotte is acting really tired. Shes not eating and when ever she has free time so usually sits and sleeps with her tail down and head down. She feels like she lost some weight and she will only eat a tomato or treats when I offer them to her, no normal chicken food. While she was sitting I actually thought for a second she was dead. Its only been going on for maybe a few days. She does have something hard in the area of her abdomen near her vent but its not that big and a while ago it felt like a water balloon. How can I help her!!!
