Selenium deficiency or??

Ok... so I've been TALKING about giving my gals a selenium boost for quite awhile - but being scared of sending them into toxicity, I haven't yet.

I'd noticed awhile ago that both of my does (ages 7 & 3 approx) stand a little weak in the back legs - with more angling in the ankle than I see in my half-grown doeling. They basically stand heavy on their heels and have the tip of their toes slightly off the ground (just barely). My older doe is definitely "weaker" in this respect than my younger one.

Both had horrible feet when I got them. They're in better shape now, but we still struggle. I think years of poor hooves has taken a toll on my older doe, as no matter what I do her back hooves seem "pinched" and very hard to get into good shape.

In any case... very recently (past week) I've noticed on the stand that my older doe is not wanting to put much weight on her left rear foot. She walks normal, no limping. She can move in all directions without appearing to favor it... I only see this on the milk stand. The other day she was standing with that foot rocked completely back on the back of the heel (frog basically pointed forward, toes up). I repositioned her foot so she was standing correctly, but she REALLY wants to stand on her heel. I just did feet a few days earlier and although it wasn't easy for her, she was able to put her weight on it while I did the other back foot. Both of them are reluctant when it comes to back feet (they handle fronts just fine) - and I'm wondering if weakness is why.

I have purchased human selenium, Vit E & Vit D and had a previous thread in which someone gave me the dosage. I just wanted to make sure this sounds like what I'm dealing with? Their coats look fine and no weird behavior. The older doe does sort of "zone out" a little... but she's always done that - and generally she's trying to get a chicken to pick her nose. No, seriously... they're buds like that. :ROFL: It's pretty gross.

So... long story short... am I safe to give selenium? Should I just do the two older does, or should I do the doeling too? If mom (the younger doe) is deficient, I'd assume baby is too, though she doesn't show any weakness (she's turning out to be QUITE a little cutie!!).
