Pretty clear she flat out lied to you. Anybody who’s had chickens and is selling them to others should know the difference between males and females and would be more knowledgeable.“The tail feathers on the one in the right are big, but it's possible that it could be a rooster, but I don't see a talons. They both came from a batch of chicks hatched in March. They could have been some of the last in that batch and are closer to 5 months. Hens begin to lay between 18 and 24 weeks and roosters usually crow at 4 to 5 months. The roosters from their batch started to crow about a month ago.” This was her response.
