if you want some really nice blues, order from WELP hat. i've raised blues for 30 + years and if breeding is a concern or desire, it is very hard to produce what you "want" with blues, because regardless of all the facts above, if you original stock is slightly off, your chicks will be as well...
i live in central nc, seeking Blue andalusian hens, pullets, chicks, no roos please,
i love the breed and have very large indoor/outdoor run that can handle what i raise. this is simply my hobby. and i'm in love with BLUES ! txs rb
