We brought home 2 bottle baby ND's last Friday. They are 16 wks old. If we leave the barn area they Baa constantly for us. Like separation anxiety. Is this just about them being babies still? Will they settle down eventually and be content with browsing by themselves? The only time they seem to go out in the barnyard to browse is when we are out there, too. Otherwise they spend all their time at the gate yelling for us to come back.
