Oh thats a tough one to read. I love Alex and have read Alex and me, along with 2 dvd's I've purchased through the alex foundation. I have this book also, but I can't get through it.
I have 2 greys and a blue front amazon. All 3 years old. They do fine. The male grey can get a little uppity at times but Pudge my zon just flies to me when she wants to be left alone.
I haven't actually had any of them dna sexed but their Vet feels confident he's correct in their gender. If he is indeed correct than I have a female amazon and a male and female grey (brother and sister from the same clutch). The "females" get a long great.
