I'm not sure that flying is a predator preventative. I think they fly up, right into the clutches of a hawk or owl. Remember, I've had Delawares free ranging for years here among the BRs, RIRs, various blue/black/splash in different breeds, EEs, Wyandottes, Buff Orps, etc. The most camouflaged birds I've ever owned are the mille fleur color Belgian D'Anvers. They can fly very well, but they also dart into a pile of oak leaves and are completely invisible. They are so small, however, that I don't free range them at all except on the rarest of occasions in warm weather when I can be outside with them. More baby pics!! Just look at this barring on a couple of them! Wow! It's almost as good as the original Stukel Rocks and one in particular is super sharp. I'm sort of guessing two cockerels, two pullets and little unknown tie-breaker. Could be wrong, but I'm veering toward that. Input gladly accepted. Check out the little one in the far back facing left-that is the one with the sharpest, finest barring. Bottom right, you can already see the cockerel's comb showing up at just over 2 weeks old.
