Steve S. Writes:
My birds have been on Harrison’s high potency for 13 years.
They are just so healthy, I don’t want to switch.
I talked to two avian vets; one said “if it’s not broke don’t fix it”, the other said it wouldn’t hurt to switch, but it wasn’t critical.
First, call Harrison’s support line at 1-800-745-7329.
They are extremely helpful and one-time doctor Harrison himself answered the phone.
Very nice guy and he really knows about birds.
