I'm thinking about purchasing a book on silkie breeding, genetics, colors and SOP. I've had a lot of people recommended buying a book on this topic to learn more about it. Every single person has suggested a completely different book, so I'm a bit lost. They seem to be quite expensive, so can anyone suggest some books that wouldn't cost so much? Under 60€ preferably if not even less. I think most books I've looked at cost 70-80+ €. Maybe there's an alternative way of learning more on this topic. I understand that they are quite pricey because these authors put all their knowledge into these books. Still I feel like browsing many different articles and websites is a bit of a messy way to learn.
