I noticed one of my girls apparently sneezing this morning. Otherwise, she appeared to be acting normally. This evening she sounds wheezy unless she is being still. I have quarantined her. There is no signs of any drainage from her eyes or nostrils. I have a total of 11 birds that are in a fairly large coop. None of the other birds seem to be having any trouble. Any advice or tips? I am os upset to have a sick girl I'm afraid that I will have to get rid of her even if she gets better.
