Sometimes they'll shed around this time of year and be ready for something to eat. I'm lucky to have 2 colubrids which have brumation/winter food strike down like clockwork and my 1 BP follows the same routine and schedule. Neither snake has eaten since October. I'll be offering food to those 3 snakes in the coming weeks and they should all be eating by mid April at the latest. With how cold this winter was, it looks like they will be coming around a little slower/later than usual. They haven't been active yet and they usually start popping their heads up in the first 2 weeks of March but my BP shed the other night so I'll be offering food tomorrow.
I'd offer again in 2-3 weeks.
