Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you today. I do apologize that your question was not answered before. Different experts come online at various times; I just came online, read about your wee one’s situation, and wanted to help.
Again I do apologize that my colleagues could not aid you sooner, but can you tell me:
How long has each had signs?
Is the discharge from the sore-eyed ewe clear or snotty/green/yellow?
Is the discharge from her nose from both nostrils or just one?
Any haze, clouding, or changes to the clear cover (cornea) over her eyes?
Any odor or other changes on the foot of the lame ewe?
Can you take a photo of each ones' issue? If you can and post them, it will let me see what you are seeing. To post them online, you can use the paper clip icon above your text box. Or if you cannot see that on your phone/computer, just post them on any site (ie Flickr, Photobucket, Imgr etc) and paste the web link here for me follow.
