Oh, I'm so sorry. Was she a Biel mix? (I know you weren't sure of their heat hardiness...)
My Naked Necks have certainly done better in the heat - but interestingly, the smaller Cream Legbars (fully feathered) seem to do almost equally well - some days, maybe even better. I'm wondering if it is the body size thing. (Though my NNs aren't THAT big.) My German New Hampshires are doing well so far, and I know other folks have some other fully feathered chickens that do well. Besides the simplistic "number of feathers" thing, what sorts of things go into a breed being heat hardy, structurally (or do we know)?
Gotta say, some folks are having temps now that would kill any bird, Naked Neck or not, so I'm not sure that replacing all our chickens with NNs would solve the problem (no that they aren't great).
