The first of our fall litters was 3 weeks old today so we took them out to weigh them. Several of them squealed really loudly when picked up. And I remember that when we were checking them in the nest box during the first week some of them squealed. They all seem to be moving and eating and growing just fine. Is there anything I should be looking for when youngsters squeal like that or just try not to startle and drop anybunny? They don't keep squealing--just that loud sharp blast of noise when they're picked up.
