I got a new dark brahma pullet yesterday (plus 5 others that are fine)--she is supposed to be about 3 months old. Yesterday her eye looked perfectly normal. This morning when I went outside to check on her, I noticed her eye was swollen shut and she seemed a little tired. She also has nasal discharge, but only on the side of the swollen eye. She isn't nearly as active as all the other chickens (they are all the same age and size as her). She is eating and drinking, but not quite as much as the others. I'm worried about her. This is my first time to have chickens and I've never had a sick one before. I'm not sure if one of the other chickens pecked her, or if it is an infection. Or if it is something else entirely different. Help! What should I do--I've read that sometimes it heals itself, but other times antibiotics are needed. What should I do?? I don't want her to loose vision in that eye, or worse die! Any suggestions are greatly appreciated!!
