Looking for some assistance with sexing and with confirmation of breed with the two chickens following. (both 12-14weeks of age)
To my understanding they are both Polish x Silkie.
I agree - first one definitely looks like a pullet while the second looks to be a cockerel. Do you have a full body picture of him/her?
The breed info you got on them appears to be true. They have the skin color of a Silkie but crowns like that of a Polish.
