I have a 8wk old German Spitzhauben, I have noticed this last wk, that it wasn't acting right..when I let everyone out of the pen, it would stay inside. It has separated itself from the rest of the flock. It was drinking and eating ok.. and running around. But yesterday it seemed to be breathing hard, when it breaths, its sides next to its beak expand and under its beak. stands in one spot all the time and head low. I took it inside, under a warm light, gave it a little sugar water.. then this morning fixed its waterer with medicated water stuff you get when they are chicks a few days old. it did eat a little tiny bit and drank a little. She or He just seems to be getting weaker then sometimes ok, at one point seemed to be having trouble standing even..it wont sit down? stool seems normal, no fluffy puffed up feathers, eyes seems ok. I held her for a long time last night she just stayed close to me. she seemed very cold when I brought her inside. I have a light I keep on in my chicken shed all the time because the weather is getting cooler at night and they are so young.. haven't been fully feathered out for long. I haven't heard her cough or sneeze. I am very careful to keep my feeders and waterer clean. If anyone has any ideas please let me know. I am new at this.
