Sorry, just jokes. The same thing just happened to me. The employee insisted he knew which chicks were which, and 100% gave my husband all the wrong chicks. One of which looked very similar to yours, and turned out to be male.

Your mileage may vary. It's clearly way too soon to tell sex anyway.
My chick was in a bin marked with various things, Starlight Green Eggers, but also assorted Marans and/or sex links? I assumed it meant sex linked Marans, but who knows, since the feedback I'm getting says mine looks like a red sex link. I still don't know if he could be a SGE and I may never know.
What did the bins allegedly say? Did you happen to notice? All that to say, we can get a better idea if we know what the bins said, but even that may not be super accurate.
Super cute lil floofer!
