An ideal diet would include, seeds, nuts, fruits, vegetables and possibly some form of pellet diet as a supplement. They must be on a good diet long before you see the first egg to insure optimal fertility. Extra calcium is often needed in the hen's diet and a good natural source for calcium is almonds. Nuts are readily eaten by macaws. Breeding The decision to breed any animal should be made with great care.
Breeding requires a great deal of commitment, time and expense.
Blue and Golds, Scarlets, Militarys and Greenwings would likely produce young faster and more reliably than Buffon's or Hyacinth Macaws. I would suggest that a beginner start with some of the easier species first to determine whether this is really what they want to do. Many macaws are produced that are not good breeding potential. You want to find healthy, full sized birds that have been raised by long time breeders that will stand behind their birds. Our most consistent breeding success from macaws has come from captive bred stock.
