Our expert says:
It can take a while for pairs to breed - they need to settle, and have just reached sexual maturity. You'll have to ensure the birds are receiving a balanced diet (not only seed), and breeding pairs often need to have shade netting in front of the enclosures to encourage breeding (they like their privacy). Some pairs also never bond - African greys can be very particular- many breeders will let all the birds into one big enclosure so they can choose their mates, and then pair them up.
I suggest your friend joins one of the many bird breeding societies - they can be founts of information.
