Hello - thank you for taking the time to help me, I have a 4 year old BO that was super healthy a week ago. Yesterday I noticed that her tail was down and drooping. Today when I checked on her, her comb had fallen over, it had lost much of its color and she is now making small gasping noises and is opening her mouth unusually wide, it appears in order to breathe air. If you have any idea what is going on, please tell me what disease/bacteria/respiratory illness she has!! I would also really appreciate advice on what to treat her with. Thank you so much for the help - I would love to post of photo of her later when she is healthy again. Other notes: we recently bought baby chicks that we are keeping in the house until they get big enough. However, I have put them in the chicken's coop while the girls were ranging on our acre-sized property. Could there be something in terms of the BO's microbial imbalance? Also, I live in an area where it doesn't get very hot very often. Recently it has been in the low 80's during the middle of the day. THANK YOU.
