Hey there! First of all, doves are a Huge commitment. Many kids here get into doves and eventually, either drop it due to the hassle of performing with livestock or because its 'difficult' to pull it off.
Try obtaining dvds like Shimada on Doves and Doves 101 by Andy Amyx. Those help alot. My personal favourite is actually by Dave Womach. Its titled Secrets of Bird magic. Excellent stuff!
Idk if i'm allowed to do this here, but on the 13th of August, I'm conducting a lecture on Dove magic and Showmanship. I'd love to have you guys there.
