Thanks for starting this thread. I'll be a subscriber too.... It will be so interesting to hear people serious about these birds weigh in. Like you, I seem to have trouble finding an in-depth discussion of type.
Don't know if my birds are 'pets' or not...
, however, the Isabel genetics came from Buddy Henry (Tennessee, I think) via a BYCer in TN - and via CJWaldon.
Beautiful bird in post #9 -- he does look like the 'text book' pictures. Also I have great admiration for Silver-duck-wings. Those are really pretty plumage patterns. My admiration includes both males & females.
Amazon on Kindle has some good books -
The Leghorns Brown, White, Black, Buff, and Duckwing: An Illustrated Leghorn Standard with a Treatise on Judging Leghorns and Complete Instructions on Breeding, Mating and Exhibiting Kindle Edition
it's 99-cents to download.
Also noticed this book
Standard-Bred Leghorns: Brown, White Buff, Black and Silver, Duckwing, their Origin and History and Practical Qualitites, the Standard Requirements, how to Mate and Breed for Best Results Kindle Edition
by John Henry Drevenstedt (Author) Format: Kindle Edition
thinking because the title is a bit different and this one has a named author it may be a different book. It's also 99-cents.
I think it was Miami Leghorn that pointed the way to that first book.
