X2....that is a Aussie cross with some sort of crested bird. Very cute! Hard to tell if it is a pullet or a cockerel. You will probably have to wait until it crows or lays an egg.I hate to be the bearer of bad news, but funky is not even a full Australorp. He appears to be a cross between an Australorp and some type of crested chicken such as a Cevecoeur or Polish, and yes, he appears to be a rooster. Sorry.
Enjoy this cutie pie and welcome to our flock!
