Weight gain during breeding question.

loonunit: They typically ovulate at around 44mm, glowing at 25mm seems a bit small.
Maybe you're underestimating the size of the follicles?

I gather they can glow a little for quite a while leading up to ovulation? The pied glowed for a while, too, in the middle of winter. But then she stopped.

But sure, I could be underestimating. I'm palpating, so who knows what's actually going on in there.
