Guinea on the loose

The sun was beating on the greenhouse, so I opened the doors at both ends.  The west door I had to dig the snow out, and it opened on a three foot bank of snow.I didn't bother with the screen door; I figured if any birds ventured out, they'd get cold feet, literally.We left, and came back in the late afternoon, and could hear the guineas shrieking from the driveway.  Not that that's unusual, but it was unusually sustained.  So I promptly walked out to see what they'd got into now.  There was a guinea, roosted up in a scrappy alder tree.  I called HW to bring his phone and see this.Her first day out.  Since the guineas were little chicks, they've lived in the greenhouse.She was quite comfortable, settling in for a long stay.  The others in the greenhouse were going off like fire alarms We aren't together!  WE AREN'T TOGETHER!I disturbed her out of the tree and herded her along the wall of the greenhouse and she happily darted back inside.  That's when I noticed, following her and her tracks in the snow, that there weren't any departing tracks.  She must have flown straight out of the door, and flown without landing anywhere, into the tree.
