The maximum weight for a Holland doe is 4 lbs. If your doe weighs 5 lbs, she is fully 25% over the maximum allowable weight. Looking at the length of her ears, I suspect that this isn't a weight problem, it's a size problem. A Holland's ears are supposed to hang down no further than 1 inch below its chin; your girl's ears look to hang well below that. Your doe is a really cute bun, but I'm wondering if she might be a really good, typey 'false dwarf." You might be able to get her weight down to 4 lbs, but her type might really suffer because she'd then be too thin.
