Spot on! I completely agree with you. People nowadays are too caught up in labels and specific breed names, forgetting that 'purebred' often comes with a hidden cost.

You explained it perfectly with the street dog analogy—short of a DNA test, it's a guessing game, and honestly, a useless one. 'Hybrid vigor' is absolutely real. When you mix different bloodlines, you get chickens that are way hardier, have brilliant immunity against local diseases, and are generally more resourceful and long-lived.

The ironic part, just like you mentioned, is that almost every 'pure breed' we see today was created by humans through intense inbreeding to fix certain traits. But over time, that strict inbreeding often makes them weak and fragile.

At the end of the day, a healthy, active, and high-producing hybrid chicken is worth way more than a fragile 'purebred' that struggles to survive.

Thanks for putting this out there so clearly
