Well I also think it depends on how many kids she has. I had one Nubian have triplet kinders and they were smaller when full grown but they are bigger than the Nigerians. One mom had a single and she was bottle raised and she is almost as big as a nubian. Some have airplane ears, some have long ears and some have upright ears. You just never know what you are going to get. I bred my kinder back to a nigerian and got smaller kids but still bigger than the nigerians even with quads born. Hope that helps.
