Her eyes and nose are clear but she cant breathe very well. and what I am guessing is an occasional sneeze is a rather violent motion of her body in which she also makes a skwaking noise I have her separated from the others in a warm place in the house. Her BM's are normal and I have been able to coax her into drinking but she is not eating. I have not seen this before in my chickens. All the others are doing well. What advice do you have?
