Hmmm not sure about those seedlings but I would guess they probably wouldn't like it...only one way to find out though. Great looking four prongers there, nice to see 'em loaded up with berries, just keep the damn rodents away!
First year seedlings (3 leafers) are on the delicate side. I would not suggest moving them the first year. Wait until the end of year two if you can.
If you had to try and relocate them that first year for some reason, I would wait until fall or late summer, when ever they have done all they are going to do for the year (turning yellow tops dyeing back), and have developed next years bud spur, and then transplant them then.
