Elderly lady is stiff in the mornings

[BellaM]

Hi everyone, one of my elderly does is stiff in the mornings, specifically her one back leg.
She's absolutely fine otherwise - hooves are in good shape, eating and drinking, pooping pellets, chewing the cud, browsing and hanging out with the other girls ... But limping a little, mostly in the morning but also if she's been lying down for a while. So I'm assuming old age is catching up with her (Nigerian Dwarf+/-10y.o).

Any suggestions for treatment or medication, preferably organic would be appreciated.

Hmmm -- south Africa. Welcome.

May limit options. Willow trees around? The leaves and young stems have aspirin like compounds. Feed them. Moringa tree leaves.
