Mercedez...."Many breeders recommend pairing a female up with more than one male, it has proven to be easier on the males during the breeding season, and usually become more prolific."
That is how it should be!!!!!!! In the wild, one female to many males.
I get upset because vasa's do need animal protein on the account of the fact that they occasionally hunt in the wild, they do NOT do well on a seed or pellet diet. Their behavior is very different than other parrots. Many baby vasa's are deficient in protein when giving a cbc when their new owners take them for their wellness exam. And 3 of the breeders that I know of in the US, do NOT breed according to their wild habits, they pair them up. This leads to unpredictable behavior. I'll give the link to my research...it's too long to post.
grab a cup of coffee for this!
but it should answer some questions, when you think about how breeders typical function....
