My girls are just over five weeks old and our Barred Rock just doesn't seem right. She's was the smallest even when we got them at two weeks and doesn't seem to have grown much since then. She eats and drinks ok but doesn't seem to have the same amount of energy as our other four. When we let them outside she pecks at the ground a little and then kind of stands off on her own until it's time for them to go in. We've been giving them all a mash of chick food and water to try and get her to eat more hoping that she'll grow but other than that we're not sure what to do. I'm worried she's just always going to seem a little off or that she'll start declining. If anyone has any advice about what we can do to help her I'd really appreciate it because at this point I'm at a loss.
