Ian i have to jump in here & tell you that you really are shorting your birds life with their diet. It would benefit both your birds to give them a well balance diet.
I just sold an alex baby to a customer who had lost her companion alex. I asked what she fed her bird & was absolutely shocked. His main diet was parrot seed, beer & salted peanuts every day, was allowed any junk food she was eating. And she thinks he died from giving him avocado. I told her i couldn't possible sell her one of my babies if she continued to feed the new baby like that.
Ian i do hope that you can change your babies to a more healthy diet of sprouts, fruit & veg. Some pellets, raw nuts. A cooked chicken bone & eggs should only be given once every couple of weeks. There is a good chance your male has a high reading of chlorestle.
