I'm thinking you have mineral out and just didn't mention it. Is that right? Other than that, it sounds like you have it covered! She sure is a pretty girl!
No, I'm not sure of that at all. She is dry and from the looks of her it's been quite awhile since she's been in milk but her bag feels lumpy on the inside.... and yes both sides feel the same.Are both halves of her udder cheesy? I would save a sample and have it tested before you start treatment. That way, if the treatment you use doesn't work, you can have a culture grown to see what type would work.
Are you sure she isn't just dried off and the milk remaining hasn't just thickened before being absorbed?
