Having the larger ones gone will give the smaller ones more of a chance to grow and flourish. They should then gain weight much faster and will be able to go to the pet shop in about 2-3 more weeks.
The smallest ones, two black marble angels, are not quite a dime in diameter, even though they are from the same clutch. Had the parents remained with them, they would have killed those to give the larger ones a better chance. But these can flourish as well and live long and happy lives. I've seen it happen!
