Need help pretty quickly. Hen is not feeling well at all. She is over a year old. Puffed up. Dirty poopy butt. Found her this morning wedged between the wall and food bin. Cold to the touch, but alive. Her poo is very watery. No discharge from mouth or nostrils. Breathing clear. She hasn't been feeling well for about a week now. Have been giving her Tetracycline ( per feed store advice). I've looked up symptoms of being egg bound. Not sure if that is it or not. She is eating if I sit there with her, but not ravenously. She has laid only one egg the whole time I have had her. Seen her drinking water. Plenty of grit available. Good quality food. Fresh vegies and greens everyday. All the other hens are in fantastic health. I have read that I should clean her butt with soap and water. But what soap? Was told Dawn will get rid of all of the oils. I am new to chickens and am learning everyday. Any advice? Should I bring her into the house? Thanks in advance for all help and suggestions.
