All 3 of my BP's have shut down. It's below zero here, has been for a while. This is my first winter with BP's and I would guess that if all three are staying in thier warm hides that this is normal.

They all ate 3 weeks ago. I am wondering:

1. Is this normal for them to shut down and do absolutely nothing?
2. When I disturb them, they appear healthy, alert and strong. Should I completely leave them alone or can I take them out once a wekk.
3. Should I feed them less often? Every 3 weeks until they begin to become more active?

Thanks!
