You guys have been so terrific with my newbie questions! Our chicks are almost 6 wks old and we are still curious about our 'bonus' chick that Murray McMurray included with the order as a 'rare, exotic' breed. We agree with several that say a SLW is not rare or exotic but nonetheless, we don't know for sure about this bird! Any thoughts on gender and is it SLW? One other dumb question....when does the terminology change from 'chick' to 'pullet' or 'cockerel'? THANKS!
