First time with quail. I have 6 hens about 8 weeks old. I've kept them together since I got them from the Co op. They are kept in an enclosed cage outside. Today I checked on them to find what looks like an injury under her eye. I cleaned her up with a cotton ball and warm water but eye looks swollen shut. I have seperate her from the others. My question is will they fight with each other? There was plenty of food and water and they have not seemed aggressive at any other time. So I'm not sure if they were picking on each other or if I have to look for something outside the pen. I'm worried about putting her back with the others.
