Wow yours are still so much bigger than mine! As of this morning their eyes haven't opened yet... My husband keeps asking when they will open their eyes. They are all about 6.5 ounces now and my little runt is 5.5 ounces.
I don't have a scale, wish I did, but didn't have the money to do so when they were born. They all have been gaining so I'm not too concerned. I am thinking the black and white one is the smallest at this point, also it hasn't opened eyes yet.
