Indigenous African chickens refused to eat their new maize. The chickens were on an estate and the head gardener told the owner that he suspected the reason was because of gene modified organisms (GMO). The woman who owned the estate promptly had the feed tested and it was discovered that their feed had been made from a GMO that included a weed and insect killer. It contained BT1 which makes the maize insect resistant, as well as Roundup which makes it weed resistant. While small quantities of BT1 and Roundup weed killer were found in the seeds, the concern remained with the cumulative effect of GM feed, not only on the chickens, but also on the eggs they produced for the family.
