Dena, I recommend you read this. It's long but worth the read. Here's a
taste of it...

PHYTOESTROGENS: PANACEA OR POISON?

The male species of tropical birds carries the drab plumage of the female at
birth and 'colours up' at maturity, somewhere between nine and 24 months.

In 1991, Richard and Valerie James, bird breeders in Whangerai, New Zealand,
purchased a new kind of feed for their birds - one based largely on soy
protein.47 When soy-based feed was used, their birds 'coloured up' after
just a few months. In fact, one bird-food manufacturer claimed that this
early development was an advantage imparted by the feed. A 1992 ad for
Roudybush feed formula showed a picture of the male crimson rosella, an
Australian parrot that acquires beautiful red plumage at 18 to 24 months,
already brightly coloured at 11 weeks old.

Unfortunately, in the ensuing years, there was decreased fertility in the
birds, with precocious maturation, deformed, stunted and stillborn babies,
and premature deaths, especially among females, with the result that the
total population in the aviaries went into steady decline. The birds
suffered beak and bone deformities, goitre, immune system disorders and
pathological, aggressive behaviour. Autopsy revealed digestive organs in a
state of disintegration. The list of problems corresponded with many of the
problems the Jameses had encountered in their two children, who had been fed
soy-based infant formula.

Startled, aghast, angry, the Jameses hired toxicologist Mike Fitzpatrick.
PhD, to investigate further. Dr Fitzpatrick's literature review uncovered
evidence that soy consumption has been linked to numerous disorders,
including infertility, increased cancer and infantile leukaemia; and, in
studies dating back to the 1950s,48 that genistein in soy causes endocrine
disruption in animals. Dr Fitzpatrick also analysed the bird feed and found
that it contained high levels of phytoestrogens, especially genistein. When
the Jameses discontinued using soy-based feed, the flock gradually returned
to normal breeding habits and behaviour.
