Ok, so it's not exactly "science" but we have our own method for predicting weather, and it's at least as valid as looking for rodent shadows.
Today our three hens each laid one egg. While that's not very exciting in and of itself, the very same thing happened yesterday too!
So, for the first time since, I think, late November or early December, all three of the hens laid two days in a row.
Pffft. Groundhogs. Who needs 'em?
Now, give me a good hedgehog and I'm right there with ya! Cute lil' guys...
