40g is fine! As M&M said, hybrids vary a lot in weight and body shape. My smallest hybrid (stephy) was 37g and my largest (franny) was 68g and almost double stephy’s size! Some will also seem quite chubby even though they have a good diet, this is usually due to Winter White genes. Campbells and some hybrids will look a lot slimmer in comparison. All 3 of my current hybrids have totally different body shapes and sizes
