Well hello there! Interesting- mine sound hoarse too! Mine are 11 weeks old, and Ive noticed the low pitched squawk when I pick them up in the evening to put them into the coop. (they like being last in..and I can't wait forever!) I took a bunch of pics last night.. some of mine seem to have copper feathers everywhere, shoulders, back, neck... they also sometimes have one white feather on each wing that looks like two little white polka dots from the back view... some have a ton of leg feathers, others not.... I have amber eyes on most of them, but one has black freckles on his eyes, and another has one wonky eye, not sure if any of these things will self correct over the next couple of months... I'd post pics (took them last night) but my phone is dead, so Ill post later.
