I noticed in the pictures you put on FB that shows your does front feet, she's sitting way back on her pasterns.
That can happen sometimes right before and after kidding when the ligaments loosen.
You should keep an eye on it.
Did you give any selenium while she was pregnant?
I hadn't even noticed, they look the same to me? And no I did not give selenium to be honest I didn't know she needed it with having loose minerals out (pro manna) but thinking about it, it does make sense I mean we have to copper bolus because they don't get enough from minerals...
I hadn't noticed her being weak in her pasterns on pictures you had posted earlier. Like I said, it does happen to some right before they kid.
As to the selenium, BoSe is an injectable that you have to get from the vet.
That's what we use. Some use an oral product that you can get, but I'm not 100% sure they have it at TSC.
