Well, the lambs might have come as a surprise, but the mud hasn't.
Round our way, spring doesn't roar in like a lion very often; it's usually more like a wet dog shaking itself, soaking everything in sight.
And because of our new water tanks, that's been both good news and bad news.
Good, because the new tank is nearly full of sparkling rainwater, but bad because the paddocks are seas of mud.
And nowhere is worse than the hen paddock, where the new tank has been installed.
On one side there is a clay mountain, left behind when the tank site was levelled.
On the other side, the clay is bare where the digger had to drive.
The flax that used to soak up some of the extra water has been excavated and I haven't yet replanted it, though I've (sort of) laid it in place.
And the track down which the plumbers wheeled barrow after barrow of gravel to use as a base for the tank? It's just sloppy mud.
Going to feed the hens is a tricky task, as you slide inelegantly down the muddy paddock carrying a bucket of wheat, while fending off the ewes which are trying to stick their whole heads into the feed bucket.
And it's not much use putting their hay out first.
They will just leave it for later when they see you coming, and go for the tasty stuff.
I've had to change the place where I feed the other sheep, too.
The overhang behind the garage has been great: big enough to shelter the hay from the rain and easy for us and the sheep to reach.
But the ground there has become a gumboot-grabbing swamp as the sheep stir up the soggy soil with their pointy little toes.
Let me tell you, anyone who has walked out of their boot and planted their foot in ankle-deep mud will be keen not to repeat the experience, especially in the sleepy early morning before breakfast.
And if you're not careful, it can be more than your foot that gets a mud pack.
So the feed station has temporarily shifted to the yards, where I can biff hay over the fence without walking in the wet spots.
But the ground will eventually dry out as the days get sunnier.
The grass has started growing, the daffodils are out and the lambs are getting ever bigger and stronger.
Soon enough I will forget the mud and be worrying about drought and dry springs.
