My sun conure is now getting ABBA 1600-C, a cockatiel mix to which I add a nut or two (depends on which kind) chopped into little pieces because she had not gotten enough protein in her previous life. Protein intake is a very difficult problem because too much is bad but too little is bad, too! So, right now, she is still on a higher protein than she would normally get so as to 'balance out' her previous lack. She is molting now which is perfectly normal as this is the season for it BUT it's the second time in less than a year as she first molted a few weeks after she came to live with me (it was the finally getting enough protein that did it) so she will continue on the higher protein for a bit longer than she would have if she had been with me for a longer time.
If you look at the ingredients ((

By the way, this is the seed mix I use for the larger species with lots and lots of roasted nuts added to it (I buy this:
