Half Siblings

I know every family is different but do you view your half-siblings the same as your full siblings? I have 3 full and 2 half and I usually only mention my full siblings because we’re closer. The 4 of us are extremely tight meanwhile our half siblings feel more like cousins or extended family members. My daughter has a half sibling as well on her dads side that she doesn’t feel very connected to. Her dad and his family live in a different state. Is it bad to feel such a disconnect towards your siblings?
