I had to enlarge the pix for myself and you may be right. The one closer does have a larger comb. If both chickens are same age. the larger comb one suggests cockerel.. You will know as soon as you hear crowing or see eggs,for sure.
Don't feel deceived, because even THE EXPERTS only get the sexing of chicks at 94% at best. Some say it is 90%. Ether way it translates to about every 10th chick being judged WRONG. Nobody does this on purpose in my view. We don't live in the perfect universe.
Well he said he knew that were pullets and I asked very specific questions then got home and called him and his story changed. He knew we were new to chickens and now he's ignoring our calls. But thank you very much for helping me
