My hen ,Peanut, has watery eyes, the right side of her face is all puffed up and she's acting a little bit slower than normal. She will eat treats and is still pecking around in the yard but she's not too interested in her food. I gave her 15 drops of 250 parts per millon collodail silver and I put 2 drops around her eye. One of my hens had this same thing about a year ago but it was worse.
