While never having a Boykin myself, I have hunted approximately 20 times per year with a buddy's 5 year old Boykin. She hunts and retrieves woodcock, snipe and grouse like a champ. She's friendly, hunts close and gets along with the other dogs in hunting camp. She has no problem tracking cripples or doing water retrieves. In November and December she hunts waterfowl in northern New England. I don't think she could carry a mature Canada goose through corn field stubble but she sure could hold em down until her handler got there. Fine gun dog. The bonus is she hunts well with our Griffs who are a versatile pointing breed.
Her breeder is Jacquelin DeAngelo. There's a description of her breeding program on the following link:

I know very little about the breed or her breeder so further research would be necessary. Others here likely know a lot more. This is just my limited experience. Best of luck!
In the photo she is on the right. The only good photo I could find of her.
