The average weight for an indian ringneck is 115gr if your babie is being weaned it should not lose more than 5% of its weight if it does then you may have to handfeed a little longer.
yeah at the moment she weighs about 100gr so i dont think i should be woried still having a bit of trouble weaning though she seems to nibble up all the pellets in to powder but not actually eat them and she is only cracking a few seeds loves her fruit and veges though
