My Rhode Island Red started loud wheezy exhaling this afternoon. She's 3 1/2 years, just finished going through a hard moult, and today she laid the first egg she's laid since late July. I know the egg was stressful since she was in the nesting box forever. Even with the noisy exhaling, she is eating, hanging out with the others, and doesn't seem distressed. Should I consider antibiotics, and if so which one? I have had no disease problems with my flock so this is new to me. Is there something I should watch for in the morning? Thanks in advance!
