Blue laced red Wyandotte.
18 weeks, pullet or cockerel? Doesn’t act like a roo, hasn’t made the sound yet, has spur buds, is a good 1/3 taller and larger than the other 10 mixed breed run, even the Olive Egger!
Also, hackle feather are roundish, as are tail feathers, no curly feathers yet?? Age is confirmed, as I’ve raised them since chicks, may be off by 7-10 days max.
