I have Primrose, whose dam is sanaan and father was a BA, and although she is white like her mum, she has taken after her dad in size, and is about twice as big as her mum was.
Re bottle feeding. One of my smaller females had twins - one male and one female, a few weeks back. She refused to feed the male kid, so I bottle fed that, and the other was left on her during the day, taken away at night. This female had no milk overnight, as she refused a bottle.
I have noticed the female (who stayed on the dam) is fatter than the male who was bottle fed.
