Good to hear the hogs are doing well.
At this time of year, I find that some of the hogs, especially females, are inclined to turn up earlier. I was caught out last night when one of the females arrived, half an hour earlier than usual, whilst I was still in the middle of hedgehog preparations. She hid in the undergrowth until the food was out and then came out and started eating as normal.
I, too, am hoping there may be some hoglets around.
