We got this chick in a batch of mixed breed brown Eggers that came to our local feed and seed from Meyer. Supposed to be a pullet. Is it a red sex-link, which they call golden buff? And I’m concerned about whether it’s really a pullet, although I think Meyer says 100% correct sexing...it’s tail feathers are coming in curled up and it likes to stand tall. First photo is at 10 days, has red stripes on back and across shoulders. Second photo almost 5 weeks. Thanks for any input!
