clear bubbles in one eye but a few days ago the eye was swollen and irritated-it looked like a bug bite or a toenail scratch which all of my girls have had at various times. Now her eye looks fine but she has a few clear bubbles coming out of it. She was broody & isolated for 3 weeks, now she's been raising babies also isolated for 2 weeks. No symptoms in the rest of the flock. She isn't rattling & her behavior is perfectly normal and she doesn't have any kind of smell. Should I be worried that she has a respitory problem or could it be a symptom of an injured eye?
