something that blundered through my mind this morning while i was wool gathering.

what triggers a hatch? i'm sure there is no one thing, but light, temperature, time of year, moon phase, what?

we are having a very mild winter so far and i was curious if there might be more hatches (or really more different hatches) right now.

recovering from ankle surgery so please don't say just get out there and watch. if i could, i might not be asking the question.
