Oh I understand, I would want to know too. Right about now she should be coming around to whatever protectiveness she may show, thought I'm not an expert so don't quote me. Also solid nerved dogs don't tend to bark obsessivly at things unless there is a threat or it has been enforced as a good behavior. The fact that she is showing alertness is a great thing and is what you want.
As for watching her. I suggest crating if you can't watch her.. only because she's not just out playing and laying down somewhere.. she is killing chickens. Do you have a fenced yard? or an area you can contain her without crating if you can't watch her?
