I have a hen around 1 year old that started squinting, acting lethargic, and tucking in her head as if she’s cold. It’s about 68 outside today and no other hens are showing these signs. I read something about a possible respiratory infection but all the treatments point to medication that is prescription only. I have no vet around me that treats poultry and with the pandemic and high price of the medication itself, it’s just not doable for me money wise. Is there anything I can do for her? Any home remedy I can try?
