I have a hen who was limping yesterday and is now hopping on one leg. She's eating fine, but looks a little puffed up and is not happy. I checked her feet and there doesn't appear to be anything wrong with them. I have noticed that she has a slight nasal discharge today. Any thoughts on what this may be? She's one of my better layers and I'd like to do whatever I can for her!!! If I could figure out how to post photos I'd post one of her. It's not Marek's I don't think because she's just picking it up, it isn't placed awkwardly or anything. And she can move it. Any help would be greatly appreciated!!!
