HI. we have a baby budgie we were hand raising. My step daughter is a new breeder and mother budgie stopped feeding this one. He is doing great, accept that he is about 7 weeks old and doesn't seem interested in eating much seed. We still have him on 2 feeds of formula a day because if we don't feed, he looks unwell and doesn't pick up until we feed him. any tips on how to wean him? should I be worried ?he flies about and seems very happy and healthy.
