that is a barred cochin cockerel the hens lay small brown eggs this one is starting to mature which is why you are getting the chest bumping and what not, in my experience with barred cochin roosters they can be pretty spunky and 2 of the 3 I've owned have become a little floggy as well. if you don't want roos then sell it I sold all 3 for 35 a piece when they were mature.
