HELP! Is this a cockerel????

Vent sexing is never more than 95% accurate under the best circumstances. What hatchery gave a 100% guarantee?

A comb like that on a 3-week-old is male.

Meyers hatchery. I’ve ordered multiple orders from them. They’re awesome. Every other one has been spot on and great chicken. Mistakes happen. They also have a 48 hour livability guarantee which they do hold up on. I had one who didn’t make it first day through the shipping and they refunded me.
