Harrison's - High Potency or Adult Lifetime?
Harrison’s recommends all birds start out and remain on High Potency for a period of 6-8 months.
Subsequent to this period, Adult Lifetime is an optional formula for some species. Most birds can remain on High Potency, but it is more expensive so some owners prefer to switch.
Some birds, such as African Grey, macaws, and larger cockatoos should remain on High Potency for life.
