Anyone know anything about Beak School?

[TiredOldMan17]

Chester the 43+ yo M2 has been with me for about 18 months. He was wild caught and doesn't like humans. I have made some progress as he actually seems to want me close but no contact.
This Beak School has been all over my ads. Wondering if anyone has any experience with their program good or bad.

Thanks for looking
Dave
