So today when i went outside to change their water and i heard a barky rough noise i thought it was a cough and it kept happening, i found the hen i haven't seperated her from the flock yet or should I? It sounds very deep and rough. I can only describe it like someone with a barky cough breathing. I don't know what it is. I think it might have to deal with the ventalation out there. My dad won't install anymore for them out there he always says they have enough but they don't. Any idea what it is and if its cureable or i should just ignore it. Thank you guys for the help.
