Two of my Rhode Island Reds have developed a cough. I was told to put some apple cider vinegar in their water, which I have been doing with no results. They've had this symptom for about 3 weeks now. About that time, they went from each laying an egg every day to nothing for 3 weeks. Other than that, they are acting normal. Any suggestions? (I'm very, very new to raising chickens)
Thanks in advance!
