They are not scared, they were bleating as it was, as kids often do. They are actually calling for her because they love her. My sister raises goats and they play with her children in this same manor. The last little black guy did have a sharpness to his bleat, he may have been feeling lonely or hungry. She probably hand feeds them once they are weened and they view her as mom.
Wait until you see what comes around the bend.
