Pregnant mare 'nesting'?

[PapaFrita]

Well, not quite nesting, but she's digging a hole in the middle of her bed and chucking the shavings up the sides. Do pregnant mares often do this? She was living out last time she had a foal, so I've got nothing to compare her behaviour to.

My old mare used to do that during the last couple of months prior to foaling. How much longer has PF got to go?

She's due in Jan, so 4 months or so
