Yesterday, we noticed our 2 year old brahma hen was sneezing quite a bit. We thought maybe she just had some dust in her lungs or something. But she is sneezing again today. I picked her up to check her over. Her breathing sounds raspy but other than that she seems fine. Her comb & face are nice and red, her eyes & beak look clear. I brought out treats and she came running as usual, so her appetite seems ok. Is there something I should do for her? I can see getting her on antibiotics if her eyes or nose seemed crusty or runny, but this is our first sick chicken, is that part coming and it would be best to head it off early? Any advice appreciated! We don't really have the space to quarantine her, but we could probably figure something out if we had to - how far away from the rest of the flock would she need to be? thanks!
